Abstract
Description
Technical Field
[0001] This application relates to the field of communication equipment technology, and more specifically to a transparent base station antenna phase shifter. Background Technology
[0002] A phase shifter is a device that adjusts the phase of a radio signal. By transmitting the radio frequency signal through a medium, a phase shift can be introduced into the signal. A phase shifter is a device that uses this principle to change the phase of a radio frequency signal. With the integration of more and more frequency bands and functional modules (such as phase shifters, filters, coaxial cables, and radiating element arrays) into base station antennas, the installation and / or operating space within the antenna is becoming increasingly limited. This severely restricts the design size of some radio frequency devices, such as phase shifters or filters. At the same time, with the development of the times and the increasing awareness of green environmental protection, the demand for aesthetically pleasing and concealed antennas is gradually increasing. Aesthetically pleasing and concealed antenna technologies can reduce people's fear of electromagnetic radiation and blend harmoniously with the surrounding environment. However, traditional phase shifters still need improvement in terms of structure and aesthetics. Summary of the Invention
