Problems solved by technology

The early hybrid ring was made of waveguide, with large power capacity, suitable for radar antenna transceiver switch, but it has the disadvantages of large volume, bulky, expensive and difficult to integrate [1]-[5]
Compared with the bridge with waveguide structure, the bridge composed of microstrip lines that can transmit quasi-TEM waves has the advantages of compact structure, small size, light weight, wide frequency band and easy manufacture. [6]-[11] ; But there are problems such as radiation loss and electromagnetic interference, and the discontinuity generated by the connection between the microstrip line ring bridge and the substrate integrated waveguide device will reduce the performance of the system

Abstract

A ring type of bridge with waveguide integrated by H numbers of substrate is prepared as forming a ring waveguide structure by metalized through-holes being arranged in coaxial circle way, setting same-phase input end and reverse-phase input end as well as two output ends on ring waveguide structure, arranging metalized through-holes on media substrate coated with metal foil on both surfaces, enabling to use SIW as lead out arm of port for connecting said bridge to SIW components such as SIW antenna.

Description

technical field [0001] The invention relates to an annular electric bridge, in particular to an H-plane substrate integrated waveguide annular electric bridge. Background technique [0002] The ring bridge (also known as the hybrid ring) is a key component of the microwave and millimeter radio frequency subsystem, and is widely used in microwave circuits to realize the functions of power distribution and obtaining a certain amplitude and phase relationship between signals. The early hybrid ring was made of waveguide, with large power capacity, suitable for radar antenna transceiver switch, but it has the disadvantages of large volume, bulky, expensive and difficult to integrate [1]-[5] . Compared with the bridge with waveguide structure, the bridge composed of microstrip lines that can transmit quasi-TEM waves has the advantages of compact structure, small size, light weight, wide frequency band and easy manufacture. [6]-[11] ; But there are problems such as radiation loss...
