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 which are stacked in sequence; The circuit layer has a first circuit and a second circuit, and the first circuit and the second circuit are provided with coupling sections that are close to each other; the first ground layer and / or the second ground layer are facing or close to each other. The position of the coupling segment is provided with an adjustment area, and the adjustment area is provided with an opening for adjusting the coupling degree. An opening for adjusting the coupling degree is opened in the adjustment area of ​​the ground layer, and the current distribution of the strip line is changed by changing the shape, area and quantity of the opening, and the coupling degree is adjusted, and the coupling degree adjustment is simple and effective.

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...
