Dual polarization microstrip array antenna.

摘要

Dual polarization microstrip array antennas for high efficiency power reception or transmission of electromagnetic waves are easy to manufacture, applicable over a wide range of frequencies and angles of incidence, and permit true conformal application and high power handling. The antenna, according to an embodiment, has an array of microstrip patch antenna elements (3), wave filters (13), matching stubs (17) and rectifier terminals (15), all highly symmetrically arranged to each other on one side of a dielectric layer (19). A common ground plane (21) is provided on the other side of the dielectric layer (19). Rectifiers are connected to the terminals to produce rectified outputs of each patch antenna element (3).
