Abstract
An antenna set on a circuit board is provided. The circuit board includes a signal transmitting unit and a grounding unit. The antenna includes a conductive supporting portion, a radiator and a grounding portion. The radiator operating in a first frequency band includes a feeding branch coupled to the signal transmitting unit for receiving a feeding signal. The grounding portion is connected to the radiator through the conductive supporting portion. The grounding portion includes a slot cavity and a grounding branch. The slot cavity is extended from a top surface of the grounding portion into the interior of the grounding portion. The grounding branch is coupled to the grounding unit. A resonant cavity is formed between the radiator and the slot cavity. The resonance of the resonant cavity operates in a second frequency band.
