Description

【Technical field】 [0001] The invention relates to the field of mobile communication base station antennas, in particular to an ultra-broadband miniaturized large-tilt electric phase shifter. 【Background technique】 [0002] At present, ultra-wideband dual-polarization electronically adjustable antennas are mostly used for 4G network coverage. Especially in some occasions where the downtilt angle of the antenna needs to be adjusted frequently to achieve better coverage effect, the broadband dual-polarization electronically adjustable antenna is often used. The ideal orthogonality of the two polarizations of the antenna is very important to the polarization diversity of the client terminal, and the quality of its orthogonality is usually evaluated by cross-polarization resolution or cross-polarization ratio. However, the current ultra-wideband phase shifter has a relatively large structural size, which cannot meet the structural requirements of the miniaturized antenna, and at...
