Description

[0002] With the development of 5G technology, electrical downtilt is also an important indicator of 5G antennas. Due to the large antenna space, the phase shifter of traditional 4G antennas is mostly fed by cables welded on the cavity.

For 5G antennas, due to the limitations of space and weight, the phase shifter can no longer be connected by cables like 4G antennas. The phase shifter feeding method of conventional 4G antennas can no longer meet the requirements of 5G antennas that are miniaturized, lightweight, easy to install and can be mass-produced. Therefore, an electrically adjustable antenna coupled phase shift feeding structure is urgently needed to solve the above problems. Utility Model Content
