Dual-Polarized Dielectric Resonator Antenna Array for C-Band Applications

What is it about?

This is a high gain dual-polarized two element cylindrical dielectric resonator antenna (DRA) array excited by two orthogonally placed H-shaped apertures. The antenna has an impedance bandwidth of 9.52% (6.0–6.6 GHz) with isolation more than 40 dB between the two ports. The measured gain of the proposed antenna for both the ports is found to be 12.5 dB with a front to back ratio of 16 dB. The antenna has an overall radiation efficiency of 94% and symmetrical radiation patterns with co-polarization levels 40 dB higher than the cross-polarization in both the principal planes .
