| Abstract: | A coaxial-fed two-step rectangular dielectric resonator antenna (DRA) with wideband characteristics is studied theoretically and experimentally. The fundamental TE111 mode of the rectangular DRA features some attractive properties, such as a low radiation Q factor and broadside radiation patterns. In this paper, a two-step rectangular DRA is fed by means of a probe placed in direct contact with one facet of the structure. This results in the excitation of three modes with similar radiation characteristics. Therefore, tri-band or wideband operation can be achieved, if these modes are designed to resonate at nearby frequencies. Over 47% impedance bandwidth is obtained, while the polarization and the radiation patterns remain remarkably stable. |
