Design of an efficient miniaturized UHF planar antenna

In this paper the design aspects and the measured results of a novel miniaturized planar antenna are described. The topology of an efficient, miniaturized, resonant slot antenna is presented and its radiation, input impedance, and bandwidth characteristics are investigated. This class of antennas can exhibit simultaneous band selectivity and anti-jam characteristics in addition to possessing a planar structure and low profile, which is easily integrable with other RF and microwave circuits.
