Abstract
An antenna/amplifier includes a waveguide and an amplifier system. The amplifier and signal lines which terminate in orthogonal probes are carried on a common substrate. The orthogonal probes are spaced from a waveguide wall and isolated for good cross polarization by a post which extends from the wall. The probes have probe tips which are spaced from the post by a probe space. Parameters which include the probe space, the impedance of the signal lines and the length of the signal lines can be selected to present an optimum impedance to low-noise amplifiers of the amplifier system.
