Compact wideband microstrip array antenna with beam squint

摘要

A compact wideband microstrip array antenna with a squint beam is introduced without the matched load. Its measured beam is at 10 offset to the broadside with a measured gain of 12 dB at 10 GHz. The measured impedance bandwidth (voltage standing wave ratio (VSWR) 2) is over 16%, which agrees well with the simulated one. It is a low-cost wideband design with compact simple structure, suited for military and commercial application.
