Abstract

An antenna includes a resistive element formed in a casing, and a feed line formed in the casing and electrically coupled to the resistive element. The positioning of the resistive element and the feeding is such that the feed line is approximately perpendicular to the resistive element. The positioning of the feed line and the resistive element may result in the antenna being sized to allow integration of the antenna into a sensor head.

Claims

1. An antenna comprising:

a resistive element formed in a casing; and

a feed line formed in the casing and electrically coupled to the resistive element, the positioning of the resistive element and the feeding being such that the feed line is approximately perpendicular to the resistive element.

2. The antenna of claim 1, wherein the resistive element is a resistive vee.

3. The antenna of claim 1, wherein the positioning of the feed line and the resistive element results in the antenna being sized to allow integration of the antenna into a sensor head.

4. The antenna of claim 1, further comprising radar-absorbing material surrounding the feed line.
