Lens-Fed Microwave and Millimetre-Wave Receivers with Integral Antennas

Abstract

A family of microwave receivers is described with antenna and semiconductor components integrated on a common substrate, in a space small enough for packing into arrays. The antenna pattern is suitable for feeding via a dielectric lens, and a balanced mixer and I.F. amplifier are integrated on the antennas. Such receivers have been built to operate around 10 and 35 GHz, and show conversions loss similar to more conventional designs.
