Millimeter Wave Grid Array Antenna for Wireless Power Transmitter

This paper proposes the geometry and simulation results of a millimeter wave grid array antenna suitable for wireless power transmission applications. The antenna generates two radiation patterns - sum and difference, depending on the feed positions which enables the target localization along with transmission. The gain level for sum pattern and null depth for difference pattern at the boresight are 12.68 dBi and -11.4 dBi respectively as per the simulation for 60 GHz. The difference to sum ratio is 24.08 dB.
