Abstract

Disclosed are a broadband phase shifter and a designing method therefor in the technical field of phase shifters, comprising a strip line and a conversion part. The conversion part is arranged on the strip line, and the strip line is disconnected and reconnected through the conversion part for realizing 180° phase inversion at this position. The strip line is a double-layer microstrip line, and the conversion part is arranged on one or more groups of the double-layer microstrip lines. The conversion part is an electrical connection part and is located at any position on the double-layer microstrip line. The double-layer microstrip line is flexible in wiring, and is used for realizing symmetrical designs when designing phase inversion frequency shift. The lengths of the double-layer microstrip line can be symmetrical lengths for realizing phase inversion phase shift, or the lengths of the double-layer microstrip line are asymmetrical lengths for regulating the phase shift to realize the phase shift of approximately 180°. The present invention is easy to integrate, has a small volume and a broad frequency band, can cover a plurality of frequency bands in combination with the design requirements of a power divider, and is used for a microstrip antenna and a microstrip feed system.

Description

technical field [0001] The invention relates to the technical field of phase shifters, in particular to a broadband phase shifter that can be used in microstrip antennas and feed systems and a design method thereof. Background technique [0002] The rapid development and application of mobile communication technology has effectively promoted the development of modern communication in the direction of miniaturization, integration, and multiple frequency bands. Microstrip antennas and feed networks have the advantages of low price, good integration, and easy processing, and are widely used in wireless communication systems. However, there are not many phase shifters that match the microstrip antenna and microstrip feed network, and their design is usually highly frequency-related and poor in versatility, which has become one of the bottlenecks restricting technological progress. Phaser has become one of the hotspots of research at home and abroad. [0003] Usually, the micro...
