Abstract
A horn antenna element includes a septum polarizer configured to transform a linear polarized input signal into a circular polarized output signal at a common port, and a horn radiator. The horn radiator includes an input geometry formed as a quad-ridge waveguide to receive the circular polarized output signal at the common port and an aperture grid to radiate a grid-based circular polarized output signal. The septum polarizer is embedded in the quad-ridge waveguide at the common port.
