摘要

A wideband dielectric resonator antenna with double-port inverted L-shaped feeders is designed. The antenna consists of two cylindrical dielectric resonators, two inverted L-shaped microstrip lines, a dielectric substrate, and a ground surface. Two inverted L-shaped microstrip lines are etched with a rectangular groove to improve the isolation. The antenna is fed by two inverted L-shaped microstrip lines connected by two ports to excite two cylindrical dielectric resonators respectively to radiate energy. According to the ANSYS20 simulation results, the reflection coefficient S11＜-10dB, the antenna center frequency is 28.35GHz, the impedance bandwidth reaches 59.6% (18.78GHz-35.7GHz), the gain reaches 7.3dBi, and the isolation in the passband is less than -10dB. The passband of the antenna covers the millimeter wave frequency band and has a good application prospect.
