Abstract

Antenna radiator, consisting of two plate-like or film-like parts (1, 2) connected by their foot ends (11) to each other and to the supply connection of the antenna. To reduce especially current and voltage losses, the radiator parts are substantially wider at the foot (1) than at the tip (12).

Claims

1. A dipole antenna radiator comprising:

two plate-like or film-like radiator parts connected by their foot ends to each other and to a supply connection of an antenna, the radiator parts being substantially wider at their foot ends than at their tips,

wherein an edge of the radiator part on a side facing in a direction of radiation is straight while an edge opposite the direction of radiation is inclined, or wherein the edge of the radiator part on the side facing in the direction of radiation is inclined while the edge opposite to the direction of radiation is straight.

2. The dipole antenna radiator of claim 1, wherein the radiator parts are tapered from their foot end toward their tip.

3. The dipole antenna radiator of claim 2, wherein the radiator parts are tapered substantially linearly from their foot end toward their tip.

4. The dipole antenna radiator of claim 1, wherein the radiator parts are connected to each other via a narrow strip-like connecting part, the supply connection of the antenna being fitted in conjunction with the narrow strip-like connecting part.

5. The dipole antenna radiator of claim 1, wherein the radiator is fitted on a circuit plate.
