Investigation of reconfigurability for a stacked microstrip patch antenna pattern targeting 5G applications

A pattern reconfigurable stacked microstrip patch antenna is presented for 60GHz central frequency. The antenna reconfigurability is realized using shorting pins in the antenna radiating aperture. Investigation is presented for different shorting pins locations. Influence on the antenna radiation pattern and return loss is studied. Measurement results for the antenna prototype agree with simulation results. The proposed antenna can be used in a next generation cellular systems.
