Abstract:
This paper summarizes work completed and under progress on integrated corner-cube antennas and receivers at the University of Michigan. An integrated corner-cube antenna has been developed for use at millimeter-wave and terahertz frequencies. The antenna is high gain and has low cross-polarization levels (<-17dB at 222GHz and <-15dB at 119µm) in the principal planes. The monolithic approach allows the integration of a matching network and a Schottky diode at the base of the antenna to yield a low-noise monolithic 600GHz receiver. The standard corner-cube antenna, which consists of a traveling-wave antenna backed by a 90° corner reflector, has been a favorite antenna for submillimeter-wave receivers. The standard design is a 4[lambda]-1ong traveling-wave antenna placed 1.2[lambda] from the apex of the machined corner reflector. The antenna also acts as a whisker contact to a Schottky diode mounted at its base.
