A new modified microstrip‐line‐fed rectangular dielectric resonator antenna coupled with slotted ground plane for circular polarization, is proposed in this article. The circular polarization is achieved due to combination of modified microstrip‐line‐fed aperture slot on ground plane. The proposed antenna offers 3‐dB axial ratio bandwidth of 16.52% (at center frequency 3.57 GHz) in the broadside direction and −10 dB impedance bandwidth of 17.87% (at center frequency 3.58 GHz). The average gain and radiation efficiency is 4.69 dB and 74.84% in the working band. It is observed that the proposed antenna is right hand circularly polarized in broadside direction. The proposed antenna is suitable for Wi‐MAX applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:206–210, 2016
