Abstract
A patch antenna system comprises a patch antenna and preferably two sets of strip-shaped parasitic elements arranged over the radiating edges of the patch antenna. The parasitic elements are spaced away from the patch antenna. Preferably, the material placed between the patch antenna and parasitic elements is selectively deposited to introduce an air gap between the elements and the antenna while also introducing mechanical support for the elements. This selective deposition of material also relaxes the requirements for high radio frequency (RF) performance, thereby reducing cost. One advantage of this solution is that it enables circular polarization to be achieved.
Claims20
A patch antenna system, comprising:
- a patch antenna;
- and
- at least one strip-shaped parasitic element arranged over a radiating edge of the patch antenna.
A antenna system, comprising:
- an antenna;
- and
- two pairs of parasitic elements arranged over the antenna.
A patch antenna system, comprising:
- a patch antenna;
- a frame layer extending around the patch antenna;
- a membrane layer on the frame layer, the membrane laser extending over the well;
- and
- at least one strip-shaped parasitic element carried by the membrane layer over the the patch antenna.
