Electronic Beam Steering and Monopulse Receivers for Millimeter Waves

Abstract

We are developing a new approach to millimeter-wave based on periodic grids of diodes and transistors, and quasi-optical components like gratings, dielectric slabs and mirrors. The grids contain large numbers of identical devices, like Schottky diodes, MESFET's and Gunn diodes that are relatively easy to make with high yield. In addition, the component can function with some failures. Power combining is done in free space, so that the losses associated with corporate feeds are avoided. With grid technology, it should to be possible to make high-power oscillators with directive beams, high-power multipliers, electronic beam-steerers, and receivers. These should be useful in many millimeter-wave radar and communications systems and as sources for imaging arrays. So far we have been able to demonstrate phase-shifters, multipliers, and oscillators.
