摘要：

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.
