Strip line structure

Abstract

The invention discloses a strip line structure, and relates to the field of communication. The structure comprises metal grounding layers which are symmetrically arranged, and dielectric layers are arranged between the symmetrically arranged metal grounding layers; a metal layer is arranged between the dielectric layers; a power line and a radio frequency transmission line are arranged on the metal layer; a blind hole is formed between the metal grounding layer and the metal layer; hollow parts are arranged on the metal grounding layers; the two ends of the radio frequency transmission line are connected to the hollow parts on the metal grounding layers in a blind hole mode. Hole discs are arranged at the upper and lower ends of the blind hole on the outer surface of the blind hole; the hole discs are connected with a PIN of the component; the blind hole and the hole disc are not in contact with the metal grounding layer. According to the invention, the structure be used as a power line and a signal transmission line at the same time, and the low longitudinal height facilitates the flattening of equipment; meanwhile, the structure is low in loss and high in stability, chromatic dispersion cannot occur, and the hole discs are connected with PINs on a component so that the component can be connected with a power source or receive signals.

Description

technical field [0001] The invention relates to the communication field, in particular to a stripline structure. Background technique [0002] With the development of 5G technology, the requirements for mobile phone antennas are getting higher and higher. Traditional passive antennas have been difficult to meet the transmission requirements. Active antennas may become the mainstream. Active antennas require power and multiple RF connections. At the same time, the vertical height of the traditional coaxial cable is high, which is not conducive to the flattening of the equipment. A coaxial cable can only connect to one antenna, and cannot connect multiple sets of antennas at the same time, and cannot serve as a power line and a signal transmission line at the same time. Contents of the invention [0003] The technical problem solved by the present invention is to provide a stripline structure that can serve as a power supply line and a signal transmission line at the same ti...
