Abstract

In this letter, a rectangular dielectric resonator antenna (DRA) structure fed by two vertical strips with quadrature in phase is studied. Both the fundamental TE₁₁₁ and the higher order TE₁₁₃ modes can be simultaneously excited to generate a wideband circular polarization. The measured 10-dB impedance bandwidth is 32.8% from 2.7 to 3.76 GHz, under which the axial ratio is less than 4 dB. The radiation pattern and antenna gain are also studied.
