Patent Images
1. A dual band antenna for a wireless communication system, comprising:
- a conducting surface for radiating and receiving electromagnetic signals and having a first cutout part and a second cutout part, said first cutout part having a length for producing electromagnetic resonance at a first frequency range, and said second cutout part having a length for producing electromagnetic resonance at a second frequency range;
a feed point connected with said conducting surface around said first cutout part for feeding signals of said first frequency range to said first cutout part and for feeding signals of said second frequency range to said second cutout part; and
a feed line connected with said conducting surface at said feed point for feeding signals to said dual band antenna.

Abstract
An antenna structure in the shape of a conducting plate for radiating and receiving electromagnetic signals and having a first opening for producing electromagnetic resonance at a first frequency band and a second opening for producing electromagnetic resonance at a second frequency band. A coaxial cable is used to feed Signals of both frequency bands to the antenna across the first opening. The first opening can be on a deflected part of the conducting plate relative to the second opening.
