Abstract

A novel (2x2) high-gain circularly-polarized cylindrical dielectric resonator antenna array integrated with helical exciter is proposed. The array offers a maximum gain of 13.8 dBi at the operating frequency. The circular polarization is obtained by incorporating helical exciter in the array structure. A prototype of the proposed configuration integrated with helical exciter has been fabricated, tested and the idea has been verified. A good agreement has been obtained between the measured and the simulated results.
