  • Abstract
    In this paper, a novel highly linear circularly polarized active antenna with gain control is presented. A printed patch is used as the output 90° hybrid in a HEMT balanced amplifier, whose branches provide gain control based on a new biasing strategy. Low intermodulation distortion (IMD) and reduced DC power consumption are assured along The proposed radiating structure could be efficiently integrated in arrays, particularly if some amplitude aperture distribution were required and some complex modulation format were to be transmitted.
