A planar inverted-F antenna with a first operating bandwidth and a second operating bandwidth comprises a ground surface, a radiating device, a shorting device, a dielectric material, and a feeding device. The dielectric material is for isolating the radiating device from the ground surface. The feeding device is for transmitting a microwave signal. The radiating device further includes a first radiating element, a second radiating element, and a third radiating element. The first operating bandwidth is formed by the first resonance mode of the first radiating element and the second radiating element. The second operating bandwidth is formed by the second resonance mode of the first radiating element and the second radiating element and the first resonance mode of the third radiating element.
