Abstract
A planar inverted-F antenna includes a ground element, a shorting element, a radiating element, and a feeding element. The shorting element extends upwardly from the ground element. The radiating element is disposed above the ground element, and extends transversely from the shorting element. The radiating element includes a meandering strip and a flat plate. The meandering strip has opposite first and second ends. The first end of the meandering strip is coupled to the shorting element. The flat plate has a connecting side that is connected to the second end of the meandering strip and that has a length different from that of the second end of the meandering strip. The feeding element has a first end that is connected to the radiating element, and a second end that extends through and that is free from electrical contact with the ground element.
