Antenna feed structure, antenna, antenna assembly method

Abstract

The application relates to an antenna feeding structure, an antenna and an antenna assembling method. The antenna feeding structure comprises a common wall, two phase-shifting cavities, a feeding circuit arranged in the phase-shifting cavities, an avoiding groove arranged at one end of the phase-shifting cavities, and a feeding plate comprising a main plate and a protruding plate. The two sides of the main plate along a first direction are respectively provided with the protruding plates. A ground conductive layer is arranged on the side of the main plate facing the common wall, and the ground conductive layer is electrically connected with the common wall. Two signal conductive layers are arranged at intervals on the side of the main plate away from the common wall, and the two signal conductive layers respectively cover the protruding plates on the two sides of the main plate. In a second direction, the surface of the side of the common wall facing the main plate is lower than the surface of the end of the phase-shifting cavities provided with the avoiding groove, so that the protruding plates can extend into the corresponding avoiding grooves, and the signal conductive layers covering the protruding plates are electrically connected with the feeding circuit through the avoiding grooves. The antenna feeding structure is simple in structure, convenient in assembling operation, and can improve production efficiency.
