Patent ID: 8754817

Claim:
A apparatus comprising: a single radio frequency (RF) input; a dual-mode monopole antenna coupled to the single RF input, wherein the dual-mode monopole antenna is configured to provide a first resonant mode and a second resonant mode and to operate as a feeding structure to an antenna circuit that is not conductively connected to the dual-mode monopole antenna; and the antenna circuit configured to provide a plurality of resonant modes, wherein the antenna circuit comprises: a line structure coupled to ground; a strip coupled to the line structure; and a second folded arm extending back towards the line structure from a distal end of the strip, wherein the strip is disposed in parallel with a first arm of the dual-mode monopole antenna and farther away from the single RF input than the first arm, and wherein the strip is disposed to form a gap between a portion of the first arm and a portion of the strip.
