Compact Reconfigurable HF-UHF Antennas

Abstract

The development of a compact reconfigurable HF-UHF antenna is of great practical importance in mobile military communications where low visibility and high mobility are required Variations of monopole and diPOLE ANTENNAS IN USE TODAY ARE NARROWBAND AND ARE PROHIBITIVELY LARGE AND BULKY AT THESE FREQUENCIES Broadband antennas are not only large but also suffer from jamming susceptibility and undesirable complex multiplexing requirements. Development of efficient small geometry planar and reconfigurable antennas is investigated Based on a resonating slot structure small antennas that exhibit simultaneous bandselectivity and antijam characteristics, So far very small antennas using novel topologies have been developed that areas as small as (0.05lamba)2. Also efficient reconfigurability over a very wide range of frequency using electronic switches has been demonstrated, Design of DC contact efficient MEMS switches and wideband designs are also being considered.
