Embodiment 1

[0022] A six-port network based on a medium-integrated suspension line, including a medium-integrated suspension line and a six-port circuit arranged on the medium-integrated suspension line, the medium-integrated suspension line includes five layers of double-sided printing overlapping from top to bottom On the circuit board, the six-port circuit is printed on the third-layer circuit board. The six-port circuit includes four couplers connected in a ring with a strip line structure. The couplers adopt a chip design and have independent cavities.

Embodiment 2

[0024] This embodiment is further refined on the basis of the above embodiments, such as figure 1 As shown, the dielectric integrated suspension line can adopt the existing structure, including five layers of double-sided printed circuit boards 1 overlapping from top to bottom, each layer of circuit boards adopts double-sided printing technology, and the metal layers on both sides of each layer of circuit boards 2 filled with intermediate medium. The intermediate dielectric materials of the first to fifth layer circuit boards can be Fr4, Fr4, Rogers5880, Fr4, and Fr4 in sequence, and the thicknesses are 0.6mm, 0.6mm, 0.254mm, 0.6mm, and 0.6mm in sequence. Such as figure 1 As shown, the middle of the second-layer circuit board and the fourth-layer circuit board are hollowed out, thereby ensuring that an air cavity structure is formed between the third-layer circuit board and the first-layer circuit board and the fifth-layer circuit board. The second metal layer and the ninth ...

Abstract

The invention discloses a dielectric integrated suspension line-based six-port network. The dielectric integrated suspension line-based six-port network comprises a dielectric integrated suspension line and a six-port circuit, wherein the six-port network is arranged on the dielectric integrated suspension line, the dielectric integrated suspension line comprises five layers of double-side printedcircuit boards which are laminated from top to bottom, the six-port circuit is printed on the third layer of circuit board and comprises four couplers, the four couplers are annularly connected by employing a strip line structure, each coupler employs a patch design, and respective cavity of the couplers is independent. The six-port circuit has the characteristics of low loss, self assembly, integration, low cost and high integral cost performance.

Description

technical field [0001] The invention relates to the field of six-port circuits, in particular to a six-port network based on medium-integrated suspension lines. Background technique [0002] With the deepening of the information age, there is a huge demand for wireless communication products and equipment in both civilian and military fields. This makes the research on wireless systems not only have the value of scientific research, but also have practical significance to many aspects such as economy, society and national defense. The six-port technology was proposed by American researchers Hoer and Engen in the 1970s, and was originally used to measure the complex reflection coefficient of the instrument. The six-port circuit is composed of a power distribution network such as a power divider and a coupler, including two input ports and four output ports. The absolute value of the power of the four output signals contains the amplitude and phase information of the input si...
