[Featured Article] From Current to Future: Wide-Angle Beam Scanning Phased Array Antennas Wide-angle beam scanning is a critical enabler for current and future terrestrial and non-terrestrial wireless communications networks. This work comprehensively reviewed the main challenges and the associated innovative techniques and strategies. Moreover, we have discussed a potentially significant technique of enabling simultaneous multibeam scanning for future B5G and 6G.

Featured Article: Shared Impedance Noise Coupling in Radio Receivers by Yihong Qi, Yunlong Luo Radio sensitivity is important in wireless receiver systems. Excess antenna noise can reduce radiated sensitivity, known as radiated sensitivity desensitization. This happens when antennas are connected, due to shared impedance noise coupling. This paper explains how passive antennas introduce excess noise into wireless systems.

Compact and Broadband Substrate Integrated Dielectric Resonator Antenna Suitable for 5G Millimeter-Wave Communications There is currently no reported DRA design that can provide a wide bandwidth spanning from 24 GHz to 43 GHz, while maintaining a compact size (e.g., < 0.4λ0×0.4λ0×0.15λ0, where λ0 is the free-space wavelength at 28GHz) suitable for wide-angle beam-scanning applications. To solve this issue, a compact and broadband substrate-integrated DRA (SIDRA) is proposed in this article https://ieeexplore.ieee.org/document/10265196 by Jie-Er Zhang, Qinfang Zhang, Wei Qin, Wen-Wen Yang and Jian-Xin Chen #AntennaArrays #Antennas #BroadbandAntennas #Bandwidth #Substrates #DielectricResonatorAntennas #Resonant frequency #IEEE #APS #OJAP

Deployable antennas are key enablers for large antennas on small platforms. Moreover, achieving wideband and dual polarization is challenging when the antenna needs to be folded into a small stowed volume. This paper presents a deployable wideband dual polarized 4 x 4 array antenna with a novel foldable mechanism.
