Abstract

The invention discloses an antenna element suitable for a base station antenna. The antenna element comprises: a support structure which is a single part and comprises a base, a top and a wall connecting the base to the top, the wall surrounding a hollow area; a first metallization provided on a first surface area of ​​the support structure, the first a metal coating forming at least a first radiating element extending along the wall from bottom to top; and a second metal coating disposed on the second surface region of the support structure, the second metal coating forming at least a first radiating element for the first a feeder circuit. The first surface region of the support structure and the second surface region of the support structure are arranged opposite each other, and wherein the first surface region or the second surface region adjoins the hollow region.

Description

technical field [0001] The present invention relates to the field of antennas, and in particular to an antenna element for a base station. Background technique [0002] Antennas for base stations used in mobile communication networks are usually array antennas consisting of several dipoles (radiators) in a crossed arrangement to generate +45° and -45° polarization. To produce such dipoles, different techniques are usually used. A conventional solution is to use die-cast radiators combined with additional plastic parts or etched planar radiators consisting of several planar substrates (PCBs) and additional plastic parts. [0003] Typically, radiator production is characterized by the following several time-consuming production steps. E.g: [0004] Parts are aligned. [0005] Solder the radiator parts together to provide electrical contact. [0006] Assembling additional plastic parts for mechanical (stability) or electrical (matching and mode correction) reasons. [000...
