Abstract
The antenna has an antenna element (212) and a feed tower (202, 402) for forming a feed to the antenna element (212). In addition, the antenna has a dielectric support plate (211, 411), which is mechanically fastened to the first end of the feed tower (202, 402). The antenna element is in the form of a folded dipole, and it consists of metal strips (413, 413′, 414, 414′, 416, 416′, 417, 417′, 716, 716′, 717, 717′, 719) connected with each other on at least two surfaces of the dielectric support plate (211, 411). At said first end, the feed tower (202, 402) is electrically connected to two different points of the antenna element (212).
Claims16
An antenna for a radio device, comprising a first antenna element and a feed tower for implementing a feed to the first antenna element, wherein
- the antenna has a dielectric support plate, which is mechanically attached to a first end of the feed tower;
- the first antenna element is a folded dipole by shape made from metal strips connected with each other on at least two surfaces of said dielectric support plate;
- and
- the feed tower is electrically connected to two different points in the first antenna element at said first end.
A method for manufacturing an antenna structure, comprising steps:
- constituting a first antenna element with a shape of folded dipole from metal strips connected to each other on at least two surfaces of a dielectric support plate;
- and
- fastening the dielectric support plate mechanically to a first end of a feed tower so that the feed tower is electrically connected to two different points in the first antenna element at said first end.
