Abstract:
An antenna for electrical coupling to a wireless communication circuit includes a first conductive strip segment having a first length, a second conductive strip segment having a second length different from the first length and coupled to the first conductive strip segment at a feed point to be electrically coupled to the drive node, and a third conductive strip segment having a third length less than both the first length and the second length. A first end of the third conductive strip is coupled to the feed point and a second end is coupled to circuit ground. The first conductive strip segment provides a first specified operating frequency range at a fundamental resonance mode corresponding to the first length plus the third length, and the second conductive strip segment provides a second specified operating frequency range at a fundamental resonance mode corresponding to the second length plus the third length.
