Abstract
A patch antenna includes a dielectric substrate formed by a high dielectric coefficient material covered with a soft material. The dielectric substrate has a first surface, an opposite second surface, and surrounding side surfaces there between. The patch antenna further includes a radiating metal arm formed on at least the first surface with a thin metal layer in a specific shape, a grounding metal plate disposed on the second surface, and a parasitic metal arm extending from the grounding metal plate towards the first surface via at least one of the side surfaces. The parasitic metal arm is approximate but not connected to the radiating metal arm. The radiation metal arm further includes an enclosed slot, together with the parasitic metal arm, improve the working bandwidth and high directivity of the antenna.
