Abstract

The invention discloses an adapter and an antenna module, and belongs to the technical field of microwave transmission. The adapter is characterized in that a first grounding part and a first transmission line are arranged on a first surface of a substrate, a second grounding part and a second transmission line are arranged on a second surface of the substrate, and the first grounding part and the second grounding part are electrically connected through a first conductive through hole; the first transmission line and the second transmission line are electrically connected through the second conductive through hole, conversion connection of the coplanar waveguide and the microstrip line is achieved, meanwhile, the first groove is formed in the first grounding part, the width gradually-changing part is arranged on the first groove, the first conductive through hole is formed along the edge of the width gradually-changing part, edge radiation can be restrained, and the antenna performance is improved. It can be understood that the adapter does not need to be provided with a transition section which is gradually changed for a long distance, so that the size can be smaller, the miniaturization of elements can be realized, and the manufacturing cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of microwave transmission, and in particular relates to an adapter and an antenna module. Background technique [0002] In microwave transmission technology, an adapter is a common microwave component used for conversion and connection between different microwave transmission structures. Such as coaxial / microstrip conversion connectors, coaxial / waveguide conversion connectors, coplanar waveguide / microstrip conversion connectors. Among them, the coplanar waveguide / microstrip conversion connector is a joint that can realize the conversion from coplanar waveguide to microstrip line or from microstrip line to coplanar waveguide. The structure of the coplanar waveguide is quite different from that of the microstrip line. The central guide strip and the metal base plate of the coplanar waveguide are fabricated on the same side of the dielectric substrate, while the conduction strip and the metal base plate of the...
