Abstract
A circularly polarized antenna includes a dielectric substrate, a closed-loop radiating element, a micro-strip radiating element, a feeding element, and a grounding element. The closed-loop radiating element is formed on a first surface of the dielectric substrate. The micro-strip radiating element is formed on the first surface of the dielectric substrate, is surrounded by the closed-loop radiating element, and is coupled to the closed-loop radiating element. The feeding element is formed on the first surface of the dielectric substrate, is surrounded by the closed-loop radiating element, and is coupled to the micro-strip radiating element. The grounding element is formed on a second surface of the dielectric substrate.
