An ultra-wideband cross-dipole antenna with wide beam for dual-polarization applications

An ultra-wideband dual-polarized antenna with a wide beam is presented in this paper. By changing the arm length and the structure of connection point which is near copper connector, the ultra-wideband is achieved. The simulated results show that the 10 dB impedance bandwidth is over 90% and port isolation is higher than 31 dB, what's more, the antenna also has a ladder-shaped reflector to get wide beam from 1.5 GHz to 2.8 GHz, and the HPBW are 82°-142° in the band.
