A wideband tri-polarized antenna is presented in this letter. The proposed hybrid structure consists of a cylindrical dielectric resonator (DR) and a copper cylinder. Tri-polarized operation is achieved by exciting the HE11x and HE11y modes of the DR, and the /4 monopole mode of the copper cylinder. The resonant frequency of the monopole mode is well tuned to work cooperatively with the two HE11 modes. Only one single substrate layer is required to integrate the three balanced feedings. A prototype of the proposed antenna is built and tested. The measured overlapping impedance bandwidth of the three ports is 410 MHz (2.38-2.79 GHz), and the isolation among the three ports is also less than -27 dB across the bandwidth.
