Embodiment Construction

[0021] Figure 1 shows a typical antenna, where the thicker lines represent transmission lines, also known as feed lines. These feed lines are usually implemented using coaxial cables 10 . Each coaxial line 10 comprises a central inner conductor 2 and a peripheral outer conductor 4 with some kind of dielectric support 12 in between, see FIG. 2 . The material in the dielectric support 12 is preferably a polymer such as PTFE.

[0022] Part of FIG. 3 shows an antenna 1 comprising a housing with at least one coaxial line 10, wherein each coaxial line comprises a wall as an outer conductor 4 and a central conductor 2 placed in the outer conductor 4 as an inner conductor , as above. The coaxial line 10 is parallel to the reflector 3, has a connector connected to the coaxial line, and said connector is mechanically attached to the antenna, and the bottom plate 6 perpendicular to the reflector 3 is attached to the same reflector 3 . The connector 8 is connected to the central condu...

Abstract

An antenna (1) comprising a housing containing coaxial lines (10), where each coaxial line comprises a wall as an outer conductor (4) and a center line (2), in parallel with a reflector (3), with a connector (8) connected to the coaxial lines (10), and to antenna feeder cables and being mechanically connected to the antenna. Present invention is characterised in that the coaxial connector (8) is connected to a first end of a separate coaxial cable (7), and that the second end of the separate coaxial cable (7) is connected to the antenna coaxial line (10).

Description

technical field [0001] The present invention relates to antenna connector assemblies, and more particularly to antenna connector assemblies for use in communication antennas. Background technique [0002] A typical communication antenna consists of several radiating elements, feed network and reflector. The purpose of the feed network is to distribute the signal from a single connector to all radiating elements. Feed networks usually consist of controlled impedance transmission lines. The antenna needs to be impedance matched to a predetermined value, usually 50 ohms or 75 ohms, otherwise the power feeding the antenna will be reflected back to its source and not radiated by the radiating element, resulting in low efficiency. [0003] In the case of transmission, the signal needs to be split between radiating elements, while in the case of reception, the signal needs to be combined by the radiating elements, see Figure 1. This is usually achieved by the same network, which...
