Abstract :
CPW-fed multiple-slot antennas have been developed for active arrays and integrated antennas. This letter describes how the antenna can be engineered for a self-resonant 50-Ω input impedance for various substrate parameters, and the concepts are verified using a three-slot antenna on εr=2.2 substrate and a five-slot antenna on εr=9.8 substrate. These antennas have been integrated directly with commercial MMIC gain block chips without any matching networks to create a quasi-optical amplifier array
