Abstract
The invention provides a method of operating a patch antenna having a radiating element. The radiating patch is excited and generates a circularly polarized radiation beam solely in a single higher order mode at a desired frequency. This allows for the radiating element to have a small surface area with the radiating beam tilted away from an axis perpendicular to the radiating element. Thus, the patch antenna provides a relatively small footprint and excellent RF signal reception from SDARS satellites at low elevation angles.
