This paper presents the best suited antenna array for the hybrid beamforming in 5G MIMO wireless communication system. Investigation finds impact on the performance matric using different antenna array size. We design the transmitter antenna array of size 16×16, 8×8, 4×4, 2×2 for the 28 GHz frequency. Our intrigued of investigation and performance metric are spectral efficiency, energy efficiency and bit error rate. In this paper we shows, as the size of antenna array increase the spectral efficiency and energy efficiency will increase by great extent. We also find the bit error rate of wireless communication is reduced with the size of antenna array. Furthermore, we demonstrated our result using MATLAB as the larger size of antenna array increase beam is more steered in desired direction and reduced the side lobes in other direction.

In this paper, a single patch Antipodal Vivaldi Antenna (AVA) is designed for the improvement of gain in wideband 5G communications. The AVA has the copper at the bottom which acts as ground and copper layer at the top acts as a radiator. As the AVA flares has continuous tapering (exponential shape), it is called as tapered slot antenna. The performance of AVA is enhanced by incorporating corrugations and dielectric lens (DL). At first, corrugations are inserted to improve the frequency response. After this dielectric lens of trapezoidal shape is implemented to boost the antenna gain. The AVA with corrugations and DL (AVA-CDL) size is $60 text{mm} times 24.1 text{mm}$. It's below −12.6 dB impedance bandwidth is 23 GHz to 29 GHz which covers 28 GHz band of 5G applications. The proposed AVA provides an improved gain in the range of 2.12 dBi to 9.8 dBi and it can be used for 5G devices.

A simple structure to enhance the coupling of waveguide fed Cylindrical Dielectric Resonator Antenna (CDRA) is designed. The coupling enhancement is achieved in this structure by simply placing an FR4 sheet inside the waveguide. Simulations have been carried out using Ansoft HFSS and CST microwave studio.

Designing a dual-band circularly polarized planar array with good isolation between the two bands is a complex job. In this work this has been implemented using a novel approach of interleaving the radiating elements of both the bands over a common aperture and yet keeping the inter-element spacing within the acceptable limits. The design has been carried out at Extended C-Band to meet the objective of achieving a half power beamwidth of 5° within the constraints of minimum mass and volume. The hardware has been successfully realized and the measured return loss is better than 20dB and the isolation between the two ports is better than 30dB at the required frequencies.

This paper presents a work on characteristic mode analysis (CMA) of a dual element modified circular monopole UWB MIMO antenna operating in a range of 3.1–10.6 GHz. Initially, the structure performance analysis is conducted using characteristic modes. Once the required modal significance performance parameter is obtained then the structure is designed to verify S-parameter performance. A good agreement is noted between CMA and S-parameter results. Proposed configuration also exhibits an isolation of more than 15dB, average radiation efficiency of 94% and stable gain characteristics, which indicate the suitability to UWB MIMO applications.

The wireless communication in 5G system enhances the transmission rate and the packet delivery ratio. There are several methods to improve the performance of 5G communication based on the optima selection of Antenna parameters. In this paper, a novel bilateral antenna pattern selection (BAPS) was proposed as the optimization technique for the best selection of spectrum pattern from the antenna parameters. Based on the Direction of Arrival (DOA), the best antenna was selected optimally to achieve the higher value of gain parameter. The spectrum of the signal was estimated to form the signal pattern of an antenna with the combination of beamforming technique to represent the design of smart antenna in the 5G communication system. These spectrum selections and the pattern validation of an DOA provides the best match of antenna that are selected for the communication. This improves the high gain and the signal strength for transmission. This also reduces the noise ratio in the signal. Due to the optimal selection of antenna parameters by using BAPS technique, this will reduce the power consumption than the traditional communication system. The result analysis validates the performance of proposed optimization technique by comparing with the other state-of-art methods.

This paper presents a design of dualband frequency selective surface (FSS) element design based on SIW cavity (SIWC) technology and its performance analysis. The proposed dualband FSS is modelled using a combination of two FSS elements. A cross-slot element has been enclosed by a square slot to design the proposed shape. The structure shows dualband response at two different frequency bands C- and Ku-bands with sharp roll-off performance characteristics. The performance of the structure has been estimated using commercial CST Microwave studio. The simulation results show the higher selectively, very good isolation between the bands and stable performance characteristics compared with its equivalent conventional planar version.

In this paper, design and analysis of an Ultra High Frequency (UHF) Autodyne proximity sensor is presented. This sensor generates and transmits the tunable RF signal and receives the reflected signal. It generates the IF frequency corresponding to the Doppler shift of the received echo. It can be tuned for detection of different Doppler offsets by IF signal filtering. The sensor is based on a single transistor Clapp oscillator. It includes capacitor loaded short loop antenna in the feedback circuit to provide 180° phase shift which is required for oscillation along with the needed radiation for short range application. The sensor circuit is fabricated and tested on a 20 mil FR4 substrate with planar capacitors and inductors to minimize the production cost. The sensor can detect the movement of targets up to 13 m range.

A multi-functional metasurface structure is presented in this paper. This metasurface consists of two resonating structures printed on two FR-4 substrates, while the bottom side of the structure is completely laminated with copper. The proposed design offered absorption at 6.1 GHz frequency with 200 MHz bandwidth and polarization conversion in the X band from 7.8 to 11.9 GHz frequency band. The presented unit cell is compact with a length and width of $0.31lambdatimes 0.31lambda$ while thickness is $0.081lambda$, where $lambda$ is the free-space wavelength at 6.1 GHz. The simulation results show that the proposed structure absorbs EM wave at 6.1 GHz in the C band with angular stability of up to 70° for both TE and TM polarization. Whereas the four-fold symmetry inside the resonator provides polarization insensitivity in nature. Along with this absorption phenomenon, this proposed structure also provides a polarization conversion phenomenon in the X band from 7.8 −11.9 GHz with angular stability of up to 50°. The absorbance mechanism in the proposed structure is further explicated with the help of surface current distribution, E-field distribution, and impedance plot, whereas the polarization conversion mechanism has been explained with the help of reflection due to cross-polarization.
