DEFORMABLE PATCH ANTENNA

摘要

A deformable patch antenna (10) includes a flexible conductive patch (18) positioned a predetermined distance from a conductive ground plane (12) by a resilient dielectric slab (14). The resilient dielectric slab (14) is made of an elastic material (e.g., an elastomer) that is capable of regaining its original shape after being deformed by an external deforming force. The flexible patch (18) is also capable of regaining its original shape under the influence of the restorative force of the dielectric slab (14). In a preferred embodiment, the flexible conductive patch (18) is fed near orthogonal edges by a pair of coaxial cable feed lines (22, 24) carrying quadrature signals to generate a circularly polarized radio frequency transmit signal.
