Description

Transmission connection structure of medium phase shifter

Technical Field

The utility model belongs to the technical field of phase shifters of electrically-tuned antennas, and particularly relates to a transmission connection structure of a dielectric phase shifter.

Background

The phase shifter is used for shifting the phase of a signal by an angle, and the working principle of the phase shifter is different according to different structures. The dielectric phase shifter realizes the phase shift by generating relative movement between a dielectric plate and a PCB.

The dielectric phase shifter generally includes a PCB, a dielectric plate disposed on the PCB, and a metal cavity for supporting and accommodating the PCB and the dielectric plate, wherein a PCB and the dielectric plate disposed on both sides of the PCB form a positive polarized or negative polarized PCB assembly. In order to reduce the volume, make the structure compact, guarantee the consistency of phase shift, usually will need to be consistent to shift phase each polarize PCB assembly and cavity to merge together and design, synchronous drive.

In the prior art, the transmission connection structure of the medium phase shifter mainly comprises the following two schemes:

1. the first scheme is as follows:

as shown in fig. 1, the dielectric plate is connected to the driving device through a connecting member disposed outside the cavity: in this connection structure, the length of dielectric plate is far greater than the length of cavity 01 to the dielectric plate can stretch out from cavity 01, and simultaneously, the length of the dielectric plate of two sides about the same PCB board needs to be greater than the length of corresponding PCB board, then, anodize dielectric plate 03 and the one end that negatively polarized dielectric plate 04 stretches out cavity 01 are through a connecting piece 02 fixed connection, and drive arrangement is through being connected the motion of the positively negatively polarized dielectric plate for the PCB board of drive with connecting piece 02, thereby realizes the purpose of shifting the phase.

The connecting structure has the advantages of small number of used parts, high transmission precision, expensive price of medium raw materials and high requirement on dimensional precision of the medium plate, and not only can the cost of the raw materials be increased, but also the processing difficulty of the medium plate can be increased. In addition, the positive and negative polarized dielectric plates are fixedly connected through a connecting piece outside the cavity, and the problem of inconsistent positive and negative polarized phase shift can exist due to overlong size chains and large assembly errors.

2. Scheme II: the medium plate is connected with the driving device through two connecting pieces:

as shown in fig. 2, this structure is extended to the outside of the chamber 01 'through a connecting member i 02' directly connected to the dielectric sheet, and then connected to the driving mechanism 04 'through a connecting member ii 03'. Although the connection mode solves the problem of cost rise caused by overlarge media in the first scheme, the processing difficulty of the media is reduced. However, the number of parts is increased, the structure is complex, the problems of overlong size chain and overlarge assembly error are aggravated, and the problem of inconsistent positive and negative polarization phase shift is more prominent.
