Integrated antennas and quasi-optical device arrays

Abstract

Integrated antennas have been the focus of increasing research activity, particularly for millimeter-wave power combining and "quasi-optical" arrays. This paper reviews some of the work in integrated antennas for oscillator and amplifier arrays carried out at UCSB. This includes unusual phenomena involving coupled-oscillator systems that have led to novel beam scanning concepts for cost-effective mm-wave radar and imaging systems.
