InP-based 28 GHz integrated antennas for point-to-multipoint distribution

Quasi-optics offers an attractive means of creating moderate-power solid-state millimeter-wave transmitters. This paper presents the development of a 28 GHz oscillator, including an InP power HEMT and integrated with a planar, endfire antenna, which is used in testing metal reflectors designed for generating omni-directional patterns for point-to-multipoint distribution. Results of this work give insight into tailoring the reflectors for omni-directional active arrays.
