AI Technical Summary

Technical Problem

Existing high-gain dual-polarized antenna solutions suffer from high reflector costs, high array synthesis costs and complex designs, and difficulty in achieving dual-polarization isolation, making them difficult to integrate into compact consumer terminals. Furthermore, they suffer from high signal propagation loss and deteriorated signal-to-noise ratio at high frequencies.

Method used

The method employs slotted and slit antennas with orthogonal polarization on the dielectric layer, and achieves electrical connection through a coplanar feed layer, avoiding reflectors and power dividers. It utilizes the orthogonality of polarization to naturally suppress coupling, simplifying the manufacturing process and reducing costs.

Benefits of technology

A dual-polarized antenna with high isolation and high gain is realized in a finite plane, reducing manufacturing costs and making it suitable for Massive MIMO communication, thus solving the problem of signal attenuation in the high-frequency band.
