Abstract
Abstract A multi-resonant antenna is formed by a plurality of resonators which resonate at different frequencies. A feed member is coupled to the multi-resonant resonators. Disposed between and separating the resonators from the feed member is a dielectric substrate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
59 words
A multi-resonant antenna, comprising: a plurality of resonators being radially disposed, at least one of said plurality of resonators being resonant at a frequency different from at least another of said plurality of resonators; a circular feed member for capacitively feeding said plurality of resonators; and dielectric substrate means disposed between said plurality of resonators and said feed member.
Claim 2
Dependent Claim
59 words
A multi-resonant antenna, comprising: a plurality of resonators being radially disposed, at least one of said plurality of resonators being resonant at a frequency different from at least another of said plurality of resonators; a circular feed member for capacitively feeding said plurality of resonators; and dielectric substrate means disposed between said plurality of resonators and said feed member.
Claim 3
Dependent Claim
27 words
The multi-resonant antenna of claim 1 wherein said at least one of said plurality of resonators is perpendicular to at least another of said plurality of resonators.
Claim 4
Dependent Claim
24 words
The multi-resonant antenna of claim 1 further comprising a feed line connected to said circular feed member at a center of said circular member.
Claim 5
Dependent Claim
17 words
The multi-resonant antenna of claim 3 wherein said feed line is external to said dielectric substrate means.
Claim 6
Dependent Claim
24 words
The multi-resonant antenna of claim 1 wherein each of said plurality of resonators overlay a portion of said circular feed member at its circumference.
