Patent Images
1. A dual-band monopole antenna apparatus, comprising:
- a microwave substrate;
a radiation device, formed on a surface of the microwave substrate for generating a first resonance mode and a second resonance mode, so that a first operating frequency corresponding to the first resonance mode and a second operating frequency corresponding to the second resonance mode are formed, the radiation device including;
a central radiation body for generating the first resonance mode; and
one pair of radiation arms for generating the second resonance mode, the radiation arms being positioned symmetrically on two opposite sides of the central radiation body and extended in the same directions; and
a transmission line coupling with the central radiation body and the radiation arms for transmitting signals.

Abstract
One dual-band monopole antenna composed of a microwave substrate, radiation devices and transmission line is disclosed. The radiation device includes the central radiation body and two radiation arms. The central radiation body is used to generate one resonance mode, and the two radiation arms are used to generate another resonance mode. Thus, the dual-band monopole antenna is capable of operating at two different frequencies. In practical applications, radiation arms can be put symmetrically on two opposite sides and close to the central radiation body.
