Abstract :
A simple linearly polarised dielectric-loaded horn with high aperture efficiency over two separate frequency bands is presented. The horn operates as a fundamental-mode dielectric-lined horn at the low frequency, and as a dual mode horn at the high frequency. Aperture efficiency better than 92.7% has been measured over the dual 4/6 GHz frequency band.
