An overview of ARL's low profile antenna work utilizing anisotropic metaferrites

摘要

We present an overview of the U.S. Army Research Laboratory's efforts in developing low profile and wideband antennas for tactical communications. Specifically we utilize an anisotropic magneto-dielectric substrate. This work includes the development of a flared dipole from 200 to 500 MHz, as well as a circularly polarized crossed dipole for satellite communications from 240 to 320 MHz. Each of these antennas are cavity backed with a profile of less than a fortieth of a wavelength. Finally, we give an overview of the theory of anisotropic transverse resonance to be utilized in next generation cavity backed antennas.
