Abstract

Quasioptical techniques are necessary for submillimeter mixers. Several feed antennas have been proposed to replace a conventional waveguide feed. Among them an equiangular spiral antenna is shown to have advantages of axially symmetric radiation pattern and of extremely broad frequency characteristics [1]. It was successfully coupled with a submillimeter SIS mixer [2]. It is important to find how its radiation pattern is dependent on geometrical shape of the spiral, on the position of a metal reflector behind the spiral, and on operating frequencies.
