Millimeter-wave band between 30 - 300 GHz frequencies combined with Cycle Prefix Orthogonal Frequency Division-multiplexing Modulation (CP-OFDM) is promoted to be a potential technology enabler for the fifth Generation (5G) mobile network that is based on Physical Data Shared Channel (PDSCH) in the uplink and downlink. Thus, this work which conducted a Maximum Ratio Combining (MRC) scalable CP-OFDM modulation and was based on a measurement at 60 GHz is basically proposed for New Radio (NR)-5G system. Measurements are taken between three buildings under a non-line-of-sight (NLOS) scenario for a path length of 183 m. The measured impulse response has been used to evaluate the performance of NR-5G in terms of the BER. An MRC combiner is also used to maximize the instantaneous SNR at the output of Multi-Input Multi-Output (MIMO) schemes. The expected results are verified by an outdoor mm-wave link (60 GHz) under NLOS conditions for radio access transmission, where high transmission efficiency and data rates could be achieved. Therefore, these results would motivate the use of MRC-CP-OFDM waveform for mobile communication 5G-NR in the downlink.

Small displacement detection is indispensable for the monitoring process in several fields such as the health of large building structures, landslides, monitoring of vibrations in large mechanical structures, and also in the health sector. Noncontact monitoring processes will provide an advantage in covering a large area operation. The radar system is potentially applied as a noncontact sensor. However, small displacement detection requires high resolution referring to the range resolution perspective. Detecting a small displacement on a millimeter to centimeter scale requires a very wide bandwidth. The main information to be obtained from small displacement detection is the distance of the target and the size of the small displacement. Frequency modulation continuous wave (FMCW) is a radar system that has been widely used in various fields. In this paper, a small displacement detection method is proposed by developing the detection capabilities of the FMCW radar. The ability to detect distance using beat frequency identification is maintained and phase detection is elaborated to detect small displacement without having to increase bandwidth. The experimental modeling of proposed FMCW using a vector network analyzer (VNA) was conducted in this study. The results show that the proposed FMCW system using VNA has the ability to detect small displacement with average phase shift of 0.41 radians for a 2 mm shift in the direction close to the target and 0.44 radians for the direction away from the target.

Direct current (DC) motor is extensively used in industry, education, and household appliances. The speed quality of the DC motor needs to be guaranteed from interference and uncertainty. Although the components of DC motor such as electronics and mechanics can develop plant model, its degradation and sensor noise may provide uncertainty. In addition, disturbance from the environment and overload can interfere with the performance of a DC motor. This research aims to apply the mixed sensitivity synthesis method of H-infinity robust control for optimization on speed control of DC motor model to deal with uncertainty. The mechatronics component principle model is calculated by mixed-sensitivity synthesis procedure for constructing the H-infinity controller K. The simulation and analysis of the proposed method showed that the circumstances on robust criteria and H-infinity norm are successfully satisfied singular values. The optimization controller design is robustly stable due to limited perturbations assessment, particularly as noise sensor simulation. The proposed design also provided better overshoot and smother signals.

This manuscript presented the development of a circularly polarized (CP) antenna array that implemented square ring slot in the center of the patch and the power weighting distribution method for its feeding line. This array antenna consists of 7 circular patches and is slotted by a square ring slot. Resonant frequency of the antenna design set at 9.4 GHz and its bandwidth 0.8 GHz. A power weighting distribution feeding line is implemented. This method is intended to suppress the sidelobe level of the antenna. Meanwhile, to enhance the CP properties, a square ring slot is inserted over each center of the patch. Then, to accomplish the axial ratio under 3 dB, the patch is truncated by a pair of square shapes at the 45° and -45°. The proposed antenna array has circular polarization with sidelobe level (SLL) around -15.1 dB at the frequency of 9.4 GHz. Its reflection coefficient, S11 bandwidth up to 1 GHz, then lower than -20 dB. 3 dB axial ratio obtained 0.9 GHz.

The aim of this paper is the development of a 2×2 MIMO antenna that is capable of covering the whole UWB spectrum of 3.1 - 10.6 GHz. The design starts by implementing a single element of Printed Circular Disc Monopole (PCDM) antenna on a 1.6 mm thick FR-4 substrate having a relative permittivity of 4.4. A parametric analysis, as well as slots insertion, are performed based on “Finite Difference Time Domain Analysis (FDTD)” to improve the structure performance related to the operating bandwidth. Concerning the MIMO antenna structure, a four-element configuration is investigated. Over the intended frequency band, the isolation is greater than 15 dB. The “Envelope Correlation Coefficient (ECC)”, “Diversity Gain (DG)”, and “Channel Capacity Loss (CCL)” have all been shown to improve diversity performance and are determined to be within acceptable limits. A network analyzer is used to measure the antenna structure once it is constructed. In terms of scattering characteristics and spectral efficiency, the measured and simulated are in good agreement.

This paper demonstrates the design and implementation of two dual-polarized ultra-wideband antennas for radar ice sounding. The first antenna operates at UHF (600– 900 MHz). The second antenna operates at VHF (140–215 MHz). Each antenna element is composed of two orthogonal octagon-shaped dipoles, two inter-locked printed circuit baluns and an impedance matching network for each polarization. We built and tested one prototype antenna for each band and showed a VSWR of less than 2:1 at both polarizations over a fractional bandwidth exceeding 40 %. Our antennas display cross-polarization isolation larger than 30 dB, an E-plane 3-dB beamwidth of 69 degrees, and a gain of at least 4 dBi with a variation of ± 1 dB across the bandwidth. We demonstrate peak power handling capabilities of 400-W and 1000-W for the UHF and VHF bands, respectively. Our design flow allows for straightforward adjustment of the antenna dimensions to meet other bandwidth constraints.

Autonomous vehicle requires telecommunication infrastructure to support their operations. WiFi technology is one of the available options to manifest it, and IEEE 802.11p is the communication standard for the autonomous vehicle. However, it is high cost and has low availability in some areas, and for implementation in a limited area, it is rather overpowering. This paper investigates the alternative for autonomous vehicle telecommunication infrastructure in a limited area, namely IEEE 802.11ac, as our proposal. We tested and measured our proposed telecommunication infrastructure with several scenarios and parameters, such as throughput, delay, jitter, and packet loss. The results showed that our proposal has a good performance for a simple autonomous vehicle operational platform in residential roads within an office area.

High data rates and fast transmission are indispensable for wireless telecommunications. IEEE 802.11 allocates frequency bands of 57 - 64 GHz for the Wireless Gigabit (WiGig) applications. Antennas with high gain that support high frequency are urgently needed. Reflectarray antenna is considered to fulfill the requirements due to each element of the array scatters the incident waves with a certain phase shift to compensate for the different spatial lengths of the feed to create coherent radiation in the desired direction. Moreover, the beamforming technique is counted to obtain a directional signal transmission. This paper proposes a reflectarray antenna operating at 60 GHz. The reflector antenna unit cell model consists of a square patch and a cross patch with the addition of stubs. A complete reflectarray consists of 7 × 7-unit cells in a square of 35 mm array form. The simulation results show a gain of 15.88 dBi with a beamforming of 60°.

The High Accuracy Asset Tracking (HAAT) of Bluetooth 5.1 Low Energy needs tiny antenna arrays to achieve efficient and very compact solutions. Rectangular Antenna Arrays guarantee good performances, both in azimuth and elevation in the Direction of arrival (DoA) estimation. This paper studies the eight antenna rectangular array topology, called URA8. Historically, MUSIC has been the most used algorithm on this type of array. Unfortunately in HAAT real-time applications, where it is essential to have a fast response from the DoA Locator, MUSIC, due to its high computational complexity in the peak searching over the pseudo-spectrum, may be inadequate for the scope. This paper proposes an innovative approach to reduce the complexity of this peak-searching phase: instead of only one peak-search over the complete azimuth-elevation hemisphere, we propose a two step search, the first with a reduced resolution and the latter with a fine resolution inside a proper confidence region, found in the first step. The proposed method ensures a good trade-off between computational complexity and detection performances: it turns out to approximately 6 times faster than the classic MUSIC, maintaining the same precision.
