Abstract
The invention provides a miniaturized dielectric phase shifter group and an antenna array feed network. The miniaturized dielectric phase shifter group comprises a base plate, a cover plate, dielectric blocks, transmission lines, dielectric phase shift fixed columns, a pull rod, a pull rod supporting block and wiring ports. According to the antenna array feed network, 8 power dividers, 8 power dividing rings and 16 antennas are equipped at the external part of the miniaturized dielectric phase shifter group. The beneficial effects are that the miniaturized dielectric phase shifter group and the antenna array feed network are applicable to a 1.8-2.7G frequency band, the intermodulation is low, the phase is continuous, the linearity is good, and the phase shifting range is large. The miniaturized dielectric phase shifter group and the antenna array feed network are simple in structure and easy to process.
Description
technical field [0001] The invention belongs to the technical field of radio frequency communication, and in particular relates to a miniaturized dielectric phase shifter group and a feeding network of an antenna array. Background technique [0002] In densely populated urban areas, in order to achieve good coverage, electronically adjustable smart antennas are needed. As a key component of electronically adjustable antennas, the phase shifter is used to adjust the phase of the antenna elements in the array antenna to achieve the main beam. Scanning within a certain range means achieving different downtilt angles, thereby covering cells of different areas and reducing interference to adjacent cells. At present, the 3G network has covered a large area. In December 2013, the Ministry of Industry and Information Technology issued a 4G license. Domestic operators are planning to fully cover the 4G network. At present, most 4G antennas are prefabricated downtilt base station ante...
