The teachings of the present application generally for an ultra-high frequency (UHF) antenna assembly which provides for a smaller package size with the same or better efficiency as a much larger antenna, particularly between 100 MHz to 500 MHZ. Particularly, through the combination of components and structures for implementing frequency selective surfaces (FSS) and high impedance structures (HIS) in combination with an anisotropic magneto-dielectric material, the present teachings provide for the use of both lower and higher frequency techniques through the operational frequency band and miniaturization, accurately improving the performance of UHF satellite communication antennas. Specifically improving performance in narrowband, with increases in efficiency, bandwidth, and lowered elevation angle radiation characteristics.
