摘要：
In this paper, a wideband omnidirectional dielectric resonator antenna (DRA) is proposed. The antenna contains a tri-mode dielectric resonator (DR), which is fed by a coaxial probe. The TM01, TM02 and TM03 modes can be excited at the same time to enhance the bandwidth. The proposed antenna operating at 13.25-21.32 GHz exhibits a simulated -10dB impedance matching bandwidth of 46.7% and a stable omnidirectional radiation pattern over the whole working bandwidth.
