[0004] At present, there are mainly two types of phase shifters in the industry: the first is to achieve the purpose of phase shifting by adjusting the length of the medium covering the electromagnetic wave transmission path; the second is to achieve the purpose of phase shifting by changing the length of the electromagnetic wave transmission path; among them , the first type of phase shifter includes a transmission line and a dielectric plate. By adjusting the relative position between the medium plate and the transmission line, the overlapping area between the medium plate and the transmission line is adjusted, thereby adjusting the coverage of the medium plate The length of the medium on the transmission line, however, the current phase shifter has the disadvantages of large length and few ports

The invention discloses a high-frequency five-port phase shifter, comprising a banding wire and media plates clamped on two surfaces of the banding wire; the banding wire comprises a first banding cross rod; a first port is arranged at one end of the first banding cross rod; a first connecting rod stretches out of the other end of the first banding cross rod; the banding wire further comprises a second banding cross rod; one end of the second banding cross rod is equipped with a second port; a second connecting rod stretches out of the other end of the second banding cross rod; the first connecting rod and the second connecting rod are connected; the free end of the first connecting rod is equipped with a first wave rod; the free end of the second connecting rod is equipped with a second wave rod; the solution of the high-frequency phase shifter realizing a number of ports in relatively small space is formed through rationally arranging the structure of the wave rods; and the simulation experiment shows that the invention is in accorded with the actual using demand.
Description
technical field [0001] The invention relates to a high-frequency five-port phase shifter. Background technique [0002] The base station antenna realizes the downtilt adjustment of the beam of the base station antenna through the phase shifter, which has the advantages of large adjustable range of downtilt angle, high precision, good pattern control, strong anti-interference ability, and easy control. [0003] The phase shifter is a necessary component of the base station antenna. This device adjusts the downtilt angle of the antenna beam by changing the relative phase between the antenna elements, thereby facilitating the optimization of the communication network. [0004] At present, there are mainly two types of phase shifters in the industry: the first is to achieve the purpose of phase shifting by adjusting the length of the medium covering the electromagnetic wave transmission path; the second is to achieve the purpose of phase shifting by changing the length of the el...
