Abstract
Methods and systems for extending a bandwidth of a dual-folded monopole antenna of a user device are described. A dual-folded monopole antenna includes a first folded monopole structure coupled to a single radio frequency (RF) input and a parasitic folded monopole structure coupled to a ground plane. The first folded monopole structure is configured to operate as a feeding structure to a parasitic folded monopole structure that is not conductively connected to the RF input.
