Millimeter-Wave Switched-Beam Grid-Array Antenna

An electronic switched-beam grid-array antenna (GAA) at 28.0 GHz is investigated. The proposed antenna panel includes of a sixteen-port GAA integrated with RF switching circuit that consists of five RF switches and a separate control panel. The sixteen beams can be electronically switched/steered with a beam coverage of ±22° and measured antenna gain of >14.0 dBi at 28.0 GHz.
