A Novel Enhanced Isolation Microstrip Dual-polarization Patch Antenna

抄録

A novel dual-polarization edge-fed microstrip patch antenna was designed in this letter. In order to increase the isolation between the two ports with different polarizations and reduce the working modes affected by the feed line, two-section continuous current strips were separated from the metal ground plane. The measured result shows that the antenna has a port-to-port isolation better than 28.9dB from 5.725GHz to 5.875GHz, and particularly better than 32.6dB at 5.8GHz, which is improved more than 12dB compared with traditional antennas. Besides, a dual-polarization excitationcan be realized within the single patch antenna for a single layer dielectric structure.
