Abstract

An antenna and method of manufacturing thereof. The antenna includes an integral antenna element, support and base, all manufactured from a flexible circuit material. A stiffener material is added to the flexible circuit material where needed to provide rigidity. When the antenna is mounted in an antenna system, foam is injected around the antenna to enhance stability. The antenna is made from flexible circuit material using printed circuit board manufacturing techniques and thus manufacturing can be highly automated with excellent repeatability.

Claims

1. An antenna comprising:

an antenna element made from a flexible circuit material; and

a support, integral with said antenna element, made from the flexible circuit material, said support and said antenna element being formed from a unitary piece of flexible circuit material;

a ground plane, integral with said support, made from a flexible circuit material, said support and said ground plane being formed from a unitary piece of flexible circuit material.

2. The antenna of claim 1 wherein said ground plane includes an adhesive.

3. The antenna of claim 1 wherein said ground plane includes:

a first ground plane portion having a first exposed conductive surface and a first tab extending from said first ground plane portion, said first tab having an exposed conductive surface; and

a second ground plane portion having a second exposed conductive surface and a second tab extending from said second ground plane portion, said second tab having an exposed conductive surface;

wherein said first tab makes electrical contact with said second exposed conductive surface and said second tab makes electrical contact with said first exposed conductive surface.
