摘要： A multi-frequency antenna comprises a substrate disposed on a clearance area of a circuit board, and a first resonance unit and a second resonance unit located on the surface of the substrate or within the substrate. The first resonance unit is connected to a signal feeding terminal of the circuit board and connected to the second resonance unit via a first filtering element. The first resonance unit forms the first resonance frequency of the multi-frequency antenna, and the first resonance unit, the first filtering element, and the second resonance unit all together form the second resonant frequency. The first filtering element shows a high impedance towards the signal with the first resonant frequency and a low impedance towards the signal with the second resonant frequency. Thus, an antenna with multiple resonant frequencies can be obtained. The material and manufacturing costs of the multi-frequency antenna can thereby be reduced.
