Multi-Frequency Antenna

Abstract

A multi-frequency antenna comprises a first conductor, a second conductor, a feeder conductor, a short-circuit member, a grounding plane and a feeder cable. The first conductor has a serpentine form. The second conductor is parallel to the first conductor and extends in one side of the first conductor. The feeder conductor connects the first conductor and the second conductor. The short-circuit member connects with the second conductor and extends serpentinely with an end thereof connecting with the grounding plane. The short-circuit member is arranged in one side of the second conductor and connects with the second conductor at a near-central point of the second conductor, which divides the second conductor into a first extension and a second extension. The feeder cable includes a central wire connecting with the feeder conductor and an external wire connecting with the grounding plane.
