Abstract

Several developments in RF front end technology based upon the active antenna concept are presented. RF front ends utilizing active antenna concepts have shown improvements in such areas as power added efficiency, compactness, low noise figure, and increased functionality. These improvements are illustrated with a Class F power amplifier transmitter with an integrated circular patch antenna, a circularly polarized patch antenna with integrated LNAs, a 60 GHz quasi-optics self oscillating mixer, and two designs implementing the recently developed broadband quasi-Yagi antenna
