Abstract

The characteristic mode theory gives useful insights into the physical behavior of antennas, which can be used for the design of single-feed circularly polarized antennas. For example, an antenna with any geometrical shape may be systematically modified by the characteristic mode analysis to give circular polarization. In this paper, a procedure based on the characteristic mode theory is used for the design and modification of arbitrarily shaped antennas to produce a circularly polarized radiated field at 2.45 GHz for ISM band application. By using this procedure the axial ratio of a proposed antenna has dropped to 0.05 dB without the need of employing an optimization software.
