Abstract

A novel very compact ultrawideband dielectric rod antenna with metallic reflector is presented. The desired HE₁₁mode on the rod is excited by a biconical dipole fed by a broadband tapered microstrip line balun. The input reflection remains below -10 dB from 3 up to 20 GHz. The antenna exhibits a flat gain larger than 7 dBi over the whole ultrawideband frequency range from 3 to 10 GHz approved by the Federal Communication Commission. An almost constant transient performance over a wide azimuth angle of ±40° is obtained with small dispersion.
