Abstract

The paper presents a novel method for the improvement in the bandwidths by mode merging of the circularly polarized dielectric resonator antenna (CPDRA). The results of improved axial-ratio bandwidth and impedance bandwidth is compared with the previous work. In this design, 50 \(\Omega\) terminator diverts current in such a way that adjacent exited modes get merged. Also the upper order modes are merged to the lower order modes and a significant enhancement is achieved in overlapping bandwidth. The proposed CPDRA provides axial ratio bandwidth of 53.78% (axial ratio < 3 dB) that completely overlaps by impedance bandwidth (S11 <  − 10 dB) of 67.70%. Here, low gain is used for the testing of CPDRA. It can be used as a reference antenna for testing of WLAN and vehicular antennas. The results of prototype CPDRA have been found in close agreement with the simulated one.
