Abstract:
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 having a longitudinal axis and a second cutout part having a longitudinal axis, 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, the longitudinal axis of the first cutout part being substantially aligned with the longitudinal axis of the second cutout part; 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; a coaxial cable connected with said conducting surface at said feed point for feeding signals to said dual band antenna; a grounding location formed on said conducting surface around said first cutout part whereby said coaxial cable is grounded; and a fixation structure disposed on said conducting surface around said grounding location, said fixation structure having a recess receiving said coaxial cable for providing precise fixation and grounding of said coaxial cable.
