In this study, a dual-band miniature antenna for LP-WAN covering 433MHz and 868MHZ bands is designed to fit into a 90*30mm terminal. Design methodology based on the use of two lumped components inserted in the radiating element is presented. The optimized antenna is fabricated and assembled with electronic components and battery. A measurement is performed to assess radiation performance in anechoid chamber. The terminal has a total efficiency of −6dB and −4.5dB at respectively 433MHz and 868MHz with a dipolar radiation pattern. The performance of the terminal is evaluated in a real environment and show similar performance at 433MHz and 868MHz.

The six-port measurement technique has played a major role in vector network analysis metrology, particularly within the community of national standards laboratories. Thanks to reduced hardware resource in contrast with conventional and well-established down-mixing heterodyne technique, this paper addresses the six-port technology for amplitude and phase measurements of millimeter-wave signals in the V band. In particular, guided, planar and monolithic IQ six-port demodulators are considered. Advantages and drawbacks of each solution are highlighted to provide a guide to address sensing applications.

This paper presents a Multiple Input Multiple Output (MIMO) antenna system dedicated to the [3-4] GHz band for 5G Full-Duplex applications. The system is based on the association of 2 transmitting (Tx) patches arrays and 2 receiving (Rx) single patches positioned symmetrically and close to each other to achieve polarization/pattern diversity. Thus, an isolation greater than 30 dB is achieved in the whole band between the Tx and Rx antennas in simulations and measurements. Moreover, a high gain of 6.3 dBi is obtained for the Tx antennas and a total efficiency, greater than 70 %, is provided for both Tx and Rx antennas. These results, especially in terms of isolation, can be added to analog and digital cancellation techniques to satisfy the self-interference challenge of Full-Duplex systems, which is close to 100 dB of self-interference cancellation.

Track-before-detect (TBD) algorithms make use of unthresholded measurements to perform target detection and tracking in scenarios where conventional approaches fail, as it is the case for low signal-to-noise ratio (SNR) conditions. In this paper, the track-before-detect algorithm using particle filters is applied for target detection and tracking and its performance using real-world radar data is assessed.

This work presents the design of wideband metamaterial MTM antenna loaded with frequency reconfiguration capability. The bandwidth enhancement is based on locating best point of the horizontal slot through parametric studies within the length L3. This horizontal slot is responsible for left-handed capacitor C L to improve bandwidth. Employing CSRR generate negative permittivity which result further bandwidth enhancement at lower and upper band with better matching condition. Two Pin Diode switch reconfigured the antenna from wideband antenna to dual-band antenna. Computer Simulation Technology (CST) Software was used for simulation to determine the accuracy of the technique and it operation. Wideband with bandwidth range (2.3-5.6) GHz was obtained. This wideband is reconfigured to dual band at 2.0 GHz and 5.2 GHz were obtained. Highest peak gain obtained in H-plane are 2.75dBi and 3.24dBi at 2.4 GHz and 5.2 GHz respectively. Based on the results obtained, the antenna can be used for GSM band, lower 5G band and WLAN applications band.

Combining ultra-wideband (UWB) and low-cost inertial measurement unit (IMU) by a tight coupling fashion is an effective way to provide an integrated indoor localization system with high accuracy and continuity. However, the performance of such an integrated system may be poor in the presence of undesirable geometry between an UWB target node and a number of UWB anchors. In addition, some parameters in the state vector of Kalman filter (used for data fusion) are unobservable from UWB ranges. These problems have not been discussed in detail in the literature related to UWB localization. In this paper, we analyze the performance of integrated localization under different geometries between the UWB node and anchors based on Fisher information matrix. Also, the parameter observability with respect to UWB ranges is analyzed.

Improvements to measurements of a VHF folded dipole operating at 55–65 MHz to be used as part of a radar for a mission to one of Jupiter's moons, Europa, are presented. Previous measurements using an unmanned aerial vehicle (UAV) or small unmanned aerial system (sUAS) are improved upon by reducing systematic errors and more accurately tracking distances within the measurement system on an outdoor measurement range at Jet Propulsion Laboratory (JPL). Details of the measurement system setup are presented along with a brief discussion of error sources. Comparing previously collected measurement data with the new measurements reveal an improvement of approximately 0.4 dB in accuracy with an improvement in over 1 dB for error budgets.

The evaluation and testing of the radiation characteristics of antennas are performed in antenna ranges, and in this context, in-situ measurements provide a means to verify the performance of the antenna such that its intrinsic radiation patterns are not substantially modified by its operational environment. Conventional outdoor range facilities are limited by space and cost constraints, and it would be impractical to develop such facilities for a single radar, let alone a network with a large number of radars. Continuing advances and the availability of relatively inexpensive commercially-off-the-shelf unmanned aerial vehicle systems allow the development of insitu antenna measurement systems for a wide variety of operating frequencies. Such unmanned aerial vehicle-based antenna ranges are important for polarimetric radars, and in particular for polarimetric calibration since a complete control of the measuring instrument is possible. This paper presents an update of the current in-situ antenna characterization and calibration of a radar system using an unmanned aerial vehicle developed by the Advanced Radar Research Center at The University of Oklahoma.

Researches on electromagnetics wave absorber implemented with common pattern structures have been explored for many applications. One of fundamental issues is its insufficiency in the performance, particularly bandwidth response and absorption characteristic. This paper presents the characterization of X-band wave absorber made of metasurface based on split-ring resonator (SRR). The utilization of SRR-based metasurface in the development of X-band wave absorber is intended to enhance its bandwidth response and absorption characteristic. The structure of X-band wave absorber is designed using a unit cell of metasurface composed of an SRR and a narrow thin strip implemented on different layers of 0.8 mm thick FR4 epoxy dielectric substrate. By taking the unit cell dimension of 3.80 mm × 3.80 mm, the characterization of proposed X-band wave absorber is performed. The characterization result shows that the separation of SRR in a unit cell holds an important role in achieving the desired performance of X-band wave absorber.
