Integrated Power Dividing Antenna Receivers

This article reviews four designs of highly integrated front-end receivers that use a power dividing antenna. Through this antenna, a discrete power divider function can be achieved by the antenna itself, yielding a compact receiver front-end.
Nowadays, microwave antennas are widely used, especially in achieving the objective of maximal integration for personal communication systems. These antennas can be mounted on the surface of high performance aircrafts, satellites, missiles, mobile phones and others. Integrated antennas are a combination of solid-state devices and circuits with printed antenna...
