Abstract
A low profile antenna assembly for an aircraft radome includes a reflector, a feed with a stacked array of septum polarizers, a mount, and a bracket. The feed, which includes bandpass and low pass filters, and broadwall branchline couplers, and the stacked array of septum polarizers, together determine polarization of the waves, attenuating unwanted signals and illuminating the entire reflector. The reflector comprises a portion of a parabolic reflector.
