摘要：
A novel dual-band dielectric resonator antenna(DRA) with dual-polarization is presented in this paper. It consists of a dielectric resonator, a square ground and a well designed feeding network. This antenna makes use of HEM111 mode and HEM113 mode to realize dual-band characteristics. Dual polarization is realized by exciting two orthogonal ports, and the port isolation is better than 65dB over the band of interest. For each port, the -10 dB impedance bandwidth of the lower and upper bands are given by 1.83-1.99GHz and 2.58-2.63GHz respectively. It can also achieve a peak gain of 6.5dB at the upper hemisphere for both modes.
