Movable-Antenna Array Enhanced Beamforming: Achieving Full Array Gain With Null Steering [PDF]
IEEE Communications Letters, 2023 Conventional beamforming with fixed-position antenna (FPA) arrays has a fundamental trade-off between maximizing the signal power (array gain) over a desired direction and simultaneously minimizing the interference power over undesired directions.

Dual Polarized Wide-Angle Scanning Phased Array Antenna for 5G Communication System
IEEE Transactions on Antennas and Propagation, 2022 A dual-polarized phased array antenna is presented with wide-angle scanning capability in this paper. To improve the mutual coupling in the array, a current cancellation method (CCM) is proposed by changing the current distribution on the excited unit to

Superbackscattering Antenna Arrays [PDF]
IEEE Transactions on Antennas and Propagation, 2015 This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering cross-section, normalized to the wavelength squared, of a linear array of N isotropic scatterers whose separation tends to zero is N2(N + 1 ...
