Abstract

The present invention relates to a wideband antenna with omni-directional radiation comprising two conductive arms placed on a substrate one of the two arms, called second arm, is supplied by a shielded line by using the other arm, called first arm.

Claims

1. A wideband antenna with omni-directional radiation comprising two conductive arms placed on a substrate, wherein one of the two arms, called second arm, is supplied by a shielded line by using the other arm, called the first arm.

2. The antenna according to claim 1, in which the two arms being placed on a substrate presenting two faces, at least the first arm comprises two conductive elements of identical geometry placed opposite each other on the two faces of the substrate and the second arm is supplied by a line placed in the substrate under the first arm.

3. The antenna according to claim 2, wherein the two conductive elements are connected by holes passing through the substrate and filled with conductive material.

4. The antenna according to claim 3, wherein the holes are made on the periphery of the conductive elements.

5. The antenna according to claim 2, wherein the second arm comprises two conductive elements of identical geometry placed opposite each other on the two faces of the substrate.

6. The antenna according to claim 2, wherein a circuit is integrated in at least one arm.

7. The antenna according to claim 1, wherein at least one of the arms includes a circular conductive element.
