Patent ID: 8339328

Claim:
An antenna comprising: a radiating element resonant on at least two frequencies, wherein the radiating element comprises: at least two radiating sections; and a discontinuity bridging the at least two radiating sections, wherein the discontinuity causes at least a partial reflection at ends of the at least two radiating sections, the at least two radiating sections and the discontinuity being configured such that the at least partial reflection at the ends of the at least two radiating sections causes the radiating element to be resonant on the at least two frequencies; at least two matching elements respectively corresponding to at least one frequency of the at least two frequencies; a switching element that, for a selected frequency of the at least two frequencies, is adapted to selectively electrically connect, to the radiating element, one or more of the matching elements that correspond to the selected frequency; and a radiating feed element electrically connected to the radiating element, wherein the at least two radiating sections comprise a first radiating section and a second radiating section, and the at least two matching elements comprise a first matching element and a second matching element, wherein: a combined length of the radiating feed element, the first radiating section and the second radiating section forming a first quarter wave resonator having a first resonant frequency of the at least two frequencies; a combined length of the radiating feed element and the first radiating section forming a second quarter wave resonator having a second resonant frequency of the at least two frequencies; the first matching element substantially matches an impedance at a feed point of the radiating feed element to a reference source impedance at the first resonant frequency; and the second matching element substantially matches the impedance at the feed point of the radiating feed element to the reference source impedance at the second resonant frequency.
