Abstract

A beam-steerable phased array with highly-miniaturized resonators and radiation-mode reconfigurability is studied in this paper for 28 GHz 5G cellular cognitive networks. Simple and straightforward design procedures are followed. Eight modified T-shaped slot antenna resonators with single rectangular directors have been arranged linearly across a small area at the top of the smartphone substrate, which is made of RT5880. By installing and biasing RF Diodes on the directors, the phased array can switch between end-fire and broad-side radiation modes to provide different radiation coverage. The suggested array design is exhibiting an impedance bandwidth from 27 to 29 GHz (resonating at 28 GHz). In addition, the introduced array offers several promising features such as highly miniaturized profile, well-defined radiations, wide beam steering capability, as well as sufficient efficiency and gain levels which make the suggested design suitable for cognitive communications.
