<p>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.</p> |
