Circular polarized microstrip antenna using a single feed

摘要

A microstrip antenna includes a dielectric substrate, a radiating plate, and a single feed connection. In these instances, the rectangular radiating plate is affixed to the dielectric substrate and having a center point, and the radiating patch defines a first aperture and a second aperture on opposite sides of the center point, each aperture having a center longitudinally aligned with the center point. The single feed connection is laterally offset from a point on a virtual line, wherein the virtual line is located between two opposite corners of the rectangular radiating patch and passes through the center point.
