Abstract: The present invention relates to a high-frequency radiation unit and a multi-frequency base station antenna. The high-frequency radiation unit comprises a radiator, a vibrator base, a first feeding member and a second feeding member. The distance between a first vertical section and a center line is greater than the distance between a first balun and the center line, and the distance between a second vertical section and the center line is greater than the distance between a second balun and the center line, that is, the first vertical section is disposed on one side of the first balun away from the center line, and the second vertical section is disposed on one side of the second balun away from the center line.

Abstract: The present disclosure provides a coupling structure and a resonant structure, a low frequency radiation unit, an antenna and an electromagnetic boundary to which the coupling structure is applied. The coupling structure includes at least two layers of conductors in a capacitive coupling relationship, each layer of conductors including a plurality of conductor strips side by side and having a gap, at least one of the plurality of conductor strips of the same layer having an electrical potential difference from an adjacent conductor strip during operation, and between the conductor strips of two different layers, at least one of the conductor strips of one layer having an electrical potential difference with at least one of the conductor strips of the other layer and the conductor strips of two different layers at least partially overlap in a direction of a mutual projection with each other.

Abstract: The present application provides a multi-standard-integrated antenna, comprising: a first antenna system having a Massive multiple-input multiple-output (MIMO) array; a second antenna system which has an antenna array and which operates at a set network standard, said second antenna system is a passive antenna system or an active antenna system; the set network standard is at least one of a 4G network standard, a 3G network standard, and a 2G network standard; the first antenna system and the second antenna system share a radome.
