Abstract

The invention discloses a strip line directional coupler and a coupling degree adjustment method thereof, wherein the directional coupler comprises: a first ground layer, a strip line layer and a second ground layer that are orderly stacked; the strip line layer includes a first line and a second line, the first line and the second line are provided with coupling sections that are close to each other, and the first ground layer and / or the second ground layer are provided with adjustment zones that are facing or close to the coupling sections. The adjustment zones are provided with openings forcoupling degree adjustment. The adjustment zones of the ground layers are provided with the openings for coupling degree adjustment. Via change of the shape, area and quantity of the openings, current distribution of a strip line is changed, and simple and effective coupling degree adjustment can be realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a stripline directional coupler and a coupling degree adjustment method thereof. Background technique [0002] Directional couplers are widely used in radio frequency and microwave fields. At present, the known stripline directional coupler is composed of a pair of stripline lines with parallel coupled lines, a dielectric, and upper and lower ground layers. A pair of parallel coupled lines approach each other to generate coupling, and the degree of coupling is determined by the distance between the coupled lines, the relative dielectric constant of the medium, and the structural size of the ground plane. The specific implementation usually uses multi-layer printed circuit boards, air striplines, etc., but the processing accuracy is limited. The existing stripline couplers have coupling degrees that deviate from the reference range or poor indicators, which reduces t...
