AI Technical Summary
Existing dual-polarized antennas struggle to simultaneously achieve low profile, high isolation, and wide bandwidth characteristics, and their traditional designs are complex and fail to meet modern communication requirements.
By employing a metasurface structure design, the current distribution is controlled by adjusting the size of the rectangular patch and creating gaps. This is combined with a microstrip gap feed structure to excite vertical and horizontal polarized currents, and parasitic patches are added to achieve broadband matching.
It achieves low profile, high isolation and wide bandwidth characteristics, with an antenna coverage range of 4.13GHz to 5.68GHz, a relative bandwidth of 31.6%, an isolation greater than 39dB, and a simple structure that is easy to manufacture.
