Abstract :
A dielectric-loaded quad-ridged horn antenna (DQRHA) that operates at 14-38GHz frequency band with dual-polarized character is analysed and simulated for ultra-wideband applications. The dielectric loading method using a perpendicular circular dielectric above the aperture can increase the gain of the quad-ridged horn antenna by 1-1.5dB from 17GHz to 38GHz. Simulated results of VSWR and gain prove that the DQRHA can achieve high gain from 14GHz to 38GHz with VSWR<;2 for the two ports.
