Abstract

The embodiment of the invention discloses a directional coupler and an antenna. The directional coupler comprises a floor, two micro-strip circuit boards and two dielectric boards. The two dielectric boards are respectively arranged between the floor and the two micro-strip circuit boards. The two micro-strip circuit boards are electrically connected with each other. Each of the two micro-strip circuit boards includes a first electric bridge, a second electric bridge electrically connected with the first electric bridge, two input interfaces in electric connection with the first electric bridge, and two output interfaces in electric connection with the second electric bridge.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a directional coupler and an antenna. Background technique [0002] A directional coupler is a general-purpose microwave or millimeter-wave component used to distribute input signals according to a certain power ratio. Directional couplers are widely used in various microwave circuits and can be used as power dividers for signal isolation, separation and mixing. [0003] An existing directional coupler usually includes a floor, a dielectric board and a microstrip circuit board, and the dielectric board is arranged between the floor and the microstrip circuit board. The microstrip circuit board includes a main line and an auxiliary line coupled with the main line. When a transmission signal is input into the main line from one end of the main line, part of the power is output from the other end of the main line. Due to the mutual coupling between the main line and the seco...
