Abstract

The invention discloses a small high-isolation dual-polarization medium resonator antenna. The antenna comprises an antenna structure frame, a circuit board, a first load metal sheet, a second load metal sheet, and a rectangular medium resonator. The circuit board is arranged on the antenna structure frame and is provided with an H-shaped gap feed structure. The first load metal sheet is arranged on the circuit board. The second load metal sheet is arranged on the antenna structure frame and under the circuit board. The rectangular medium resonator is arranged on the circuit board. A gap is formed between the rectangular medium resonator and the first load metal sheet, and a gap is formed between the rectangular medium resonator and the first load metal sheet. The rectangular medium resonator rotates 45 DEG around the central shaft of the circuit board, so two edges of the rectangular medium resonator are in the direction parallel to the diagonal of the circuit board, thereby forming +/- 45 DEG dual polarization.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a small high-isolation double-polarized dielectric resonator antenna. Background technique [0002] With the continuous maturity of FDD-LTE technology and the issuance of FDD-LTE licenses by the state, China's mobile communication industry has entered the comprehensive 4G era since then. As one of the core components of the wireless communication system, the performance of the antenna directly affects the quality of the entire communication network and user experience. [0003] Dual-polarized antenna technology utilizes the incoherence of orthogonal electromagnetic waves and the multipath transmission effect of signals. In the duplex mode of transmission and reception, antennas with mutually orthogonal polarizations are used to work at the same time. The signals transmitted in the wireless channel will be affected by many factors. Fading, this diversity technology can effect...
