Abstract
A circularly polarized antenna includes first and second dielectric substrates, a grounding element, a feeding element, a coupling element, and a close-loop radiating element. The grounding element is formed on a first surface of the first dielectric substrate. The feeding element is formed on a second surface of the first dielectric substrate. The second dielectric substrate is disposed on the second surface of the first dielectric substrate and overlaps the feeding element. The coupling element is formed on the second dielectric substrate. The close-loop radiating element is formed on the second dielectric substrate.
Claims10
A circularly polarized antenna, comprising:
- a first dielectric substrate having opposite first and second surfaces;
- a grounding element formed on said first surface of said first dielectric substrate;
- a feeding element formed on said second surface of said first dielectric substrate;
