Embodiment Construction

[0019] see Figure 1 to Figure 5 , the embodiment of the present invention is an equal phase differential multiplex compound phase shifter composed of four phase shifter subunits. The dielectric substrate 15 is placed flat on the lower reflection plate 02, and the front of the substrate 15 is covered with a metal material with good conductivity and a certain regular shape, such as copper, aluminum, etc., and its thickness depends on the initial specific requirements of the designer. It is fixed, generally ranging from 0.03mm to 2mm. The metal material includes the power divider subunit 04 and the fixed transmission lines 05, 06, which are distributed on the dielectric substrate 15 according to a certain regular shape, and are completely symmetrical in the longitudinal direction, such as 05a, 06a and 05a', 06a'. The phase shifter subunit and the main circuit of the power distribution subunit are connected in series to form a phase shifting power distribution network together. ...

Abstract

The invention discloses an equiphase differential multiplexed phase shifter comprising a plurality of phase shifter subunits, a plurality of power divider subunits, a metallic reflector plate, a sliding device and a positioning device for limiting the sliding stroke. The phase shifter subunits are serially connected with a main circuit of the power divider subunits and consist of fixed transmission lines which are fixed microstrip transmission lines or fixed transmission lines of strip lines and slidable transmission lines which are sliding transmission lines of microstrip lines or sliding transmission lines of the strip lines relative to the fixed transmission lines, and the fixed transmission lines and the slidable transmission lines are mutually coupled through electric signals; a plurality of slidable transmission lines are fixedly connected together and the synchronous movement of the slidable transmission lines can be ensured through the sliding device. The equiphase differential multiplexed phase shifter has the advantages that since the phase shifter and a power dividing network are comprehensively designed, the integrated degree is high; an insulated medium or air microstrip line or strip line structure is relatively simple and easy to assemble and realize in the engineering; and the equiphase differential multiplexed phase shifter is especially suitable for application on multi-array electric modulation intelligent antennae.

Description

【Technical field】 [0001] The invention relates to the field of mobile communication, in particular to an electrically adjustable antenna phase shifter for a mobile communication base station. 【technical background】 [0002] The mobile communication system is a combination of wired and wireless. It is a complex in which the mobile network connects the mobile station with the base station through the air interface (antenna) within its coverage area, and then connects with the mobile switch. Therefore, the antenna is very important for mobile communication. For the network, it plays a decisive role. If the antenna selection (type, location) is not good or the parameters of the antenna are not set properly, it will directly affect the operation quality of the entire mobile communication network. Especially in areas with a large number of base stations, small station distances, and high traffic areas with a large number of carrier frequencies, coupled with the multiple reflection...
