Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, the ...

Abstract

The invention discloses a microstrip phase shifter, and the phase shifter comprises: a first substrate which comprises a first surface and a second surface, wherein the first surface and the second surface are opposite to each other, the first surface is provided with a metal ground layer, and the second surface is provided with a first feed line and a second feed line, which are arranged in parallel; a mobile assembly which is movably arranged on the first substrate, wherein a mobile feeder line is arranged on the mobile assembly, the mobile feeder line comprises a first feed part, a second feed part and a connecting part connected with the first feed part and the second feed part, the first feed part is movably stacked on the first feeder line, and the second feed part is movably stackedon the second feed line; and a cover shell which is detachably arranged on the first substrate, wherein the moving assembly is arranged between the cover shell and the first substrate. The microstripphase shifter has the advantages of being small in size, light in weight and low in cost.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a microstrip phase shifter. Background technique [0002] With the development of communication technology, people's demand for communication quality is getting higher and higher. The new generation of 5G mobile communication technology widely adopts MIMO (massive multiple input multiple output) array antenna. The number of ports of the antenna far exceeds that of the 4G antenna. If each port is electronically adjusted, then an antenna needs a large number of phase shifters to change the phase. The design of the phase shifter is particularly critical, and the phase shifter needs to be low-cost and miniaturized while ensuring good performance. The existing technology generally adopts cavity phase shifter, which seals the circuit in the metal cavity to form a strip line, and changes the phase by moving the medium or moving the metal slider, and the metal cavity causes the ca...
