High Gain Conical Horn Antenna Integrated With a Planar Substrate for 60 GHz WPAN Applications
Résumé
A integration technique of horn antennas on conventional substrates is proposed for improving interconnections and therefore losses with planar devices. Considering Ag/Cu metallised foams, a 3D micro-machining process is employed for developing a circular horn antenna, with implicit integrated excitation structure and back side cavity. This antenna can be mounted on a conventional substrate, providing high gain value non achievable with planar antennas. Measurements are compared to simulations.
