Abstract
A novel wideband dual-polarized antenna with load of a disk is presented in this letter. The antenna is composed of two cross magneto-electric dipole antennas vertically fixed on an aluminum plate as ground plane, which are excited by two similar Γ-shaped coaxial feeder. Furthermore, in order to further broaden the impedance bandwidth, a disc-shaped resonator is loaded on the front end of the dipole. And a metal barrel reflector is loaded around the antenna to further improve the antenna's radiation characteristics. Measured results show that the proposed antenna achieves a 10 dB with bandwidth of 1.2–2.4 GHz, and its port isolation is higher than 28 dB. Moreover, stable radiation pattern with a peak gain of 7.7–9.2 dB is obtained within that band.
