Abstract :
An active microstrip antenna with self-mixing oscillator is introduced with double-ring geometry. It is simple to implement and presents a dual-frequency response in the operating range of C-band (3.7-4.2 GHz). The circuit with common-drain FET is used as an oscillator as well as a mixer. This active microstrip antenna can be applied in ROTV of satellite communication as the down converter
