Problems solved by technology
However, with the widening of the mobile communication frequency band, the ring bridge designed in the prior art has been unable to meet the broadband index. The traditional structural design, its frequency is limited within the range of f0=±0.23 f0. If the index exceeds this frequency band range, the index will be It will deteriorate sharply and cannot meet the use of communication systems, and its frequency bandwidth is limited by the traditional arc length. are not equal, so the sensitivity to frequency increases and affects performance; resulting in the use of ring bridges less and less, and then only parallel coupled line bridges can be used. The parallel coupled line bridges are bulky and inconvenient to install, and High cost, not easy to be widely used

Description
technical field [0001] The invention belongs to the technical field of electronic information and mobile communication, and in particular relates to a preparation method of a wide-band annular electric bridge and an electric bridge prepared by implementing the method. Background technique [0002] Microstrip bridges include branch line bridges, ring line bridges, etc. according to structural differences. The ring bridge (also known as the hybrid ring) is a key component of the microwave and millimeter radio frequency subsystem. The role of the ring bridge in mobile communication is mainly to synthesize or split signals. It has the advantages of small size and low cost. , has been widely used in the field of mobile communication in the past. However, with the widening of the mobile communication frequency band, the ring bridge designed in the prior art has been unable to meet the broadband index. The traditional structural design, its frequency is limited within the range of...
