Abstract

The invention relates to the technical field of mobile communication base station antennas, and discloses a dielectric phase shifter and a 5G base station antenna. The dielectric phase shifter comprises a strip line PCB, a first dielectric plate, a second dielectric plate, and a cavity with one end open. Copper foil wires are arranged on two opposite side surfaces of the strip line PCB, and starting points and ending points of the copper foil wires are positioned at the same end of the strip line PCB; the strip line PCB is fixedly arranged in the cavity; and the first dielectric plate and thesecond dielectric plate which are clamped on the two sides of the strip line PCB are installed in the cavity in a sliding mode. The dielectric phase shifter provided by the invention is large in phaseshifting amount, small in size and easy to install, and vertical installation can be realized, so that the transverse occupied size is reduced, and flexible layout is facilitated.

Description

technical field [0001] The invention relates to the technical field of mobile communication base station antennas, in particular to a dielectric phase shifter and a 5G base station antenna. Background technique [0002] Electrically adjustable antenna technology is a common requirement in mobile communication systems. This technology is used to timely change the phase of each radiating element of the antenna array to adjust the vertical beam pointing of an antenna, thereby controlling the range of communication signals. [0003] This technique is primarily implemented with phase shifters that can be used to adjust the phase of the output signal. Under the control of an external control source, by moving one part of itself, the phase shifter can change the phase of one input signal and distribute it to multiple branch output ports, thereby changing the phase of the signal transmitted to the transmitting element and realizing the beam Decline adjustment. The rapid developmen...
