Abstract: Arrays on personal terminals are feasible using mmWave frequencies, but are limited by mutual coupling. A standard specification for MIMO is −15 dB coupling which can be readily attained ...

Abstract: Most of beamforming methods rely on the proper estimation of the steering vectors of the incoming signals in order to calculate appropriate array feeding weights. However, this estimation is ...
