Abstract
A waveguide-fed microwave system particularly for cavity-backed spiral antennas for the Ka band comprises a waveguide transmission line; a microwave device having a pair of balanced, parallel feed wires; and a doubled tapered ridge transformer directly connecting the waveguide transmission line to the balanced, parallel feed wires of the microwave device providing a direct symmetrical transition between the waveguide transmission line and the microwave device.
