ABSTRACT:
A multi-frequency antenna with dual loops is provided. The antenna includes a T-shaped radiator having a first arm and a second arm of unequal lengths as a main body, and two grounded L-shaped radiators, so as to form dual loops. Thus, the antenna can operate in a high-frequency operation mode and a low-frequency operation mode. With the dual loops, the antenna obtains enough bandwidths at high frequency, and also meets the requirements of low frequency. More specific, the antenna meets the requirements of high-frequency systems, such as DCS/PCS/UMTS and those of low-frequency systems, such as AMPS/GSM.
