Abstract

A novel broadband ±45˚ dual-polarization antenna is presented. By introducing coupling slots on the loop dipole arms of the antenna, multi-resonance performance occurs so that the impedance bandwidth is greatly widened. An enhanced impedance bandwidth about 92.5% with VSWR < 2 is obtained at two ports, corresponding to the frequency region of 1.61-4.38 GHz. In the frequency range of 1.61-3.8 GHz, a gain of 8.2 ± 2.2 dBi is obtained. For the frequencies beyond 3.8 GHz, the gain drops sharply and goes down to 1.1 dBi at 4 GHz. Within the operating frequencies, a port-to-port isolation > 22.5 dB is achieved. Especially, the proposed antenna has a very simple configuration and is easy to be fabricated. A mechanical prototype of the antenna has been manufactured and measured. The measurement results have good agreement with the simulations. The work principle and detailed descriptions of the antenna are presented in the paper.
