摘要:In this paper 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 func-tionality. These improvements are illustrated in this paper with a Class F transmitter w ith 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
