Abstract:
Methods and systems for extending a bandwidth of a wideband antenna of a user device are described. A wideband antenna includes a parasitic element coupled to ground and a single radio frequency (RF) input coupled to an antenna structure at a first point. The antenna structure comprises a tapered side that tapers away from the first point to create an increasingly larger gap between the antenna structure and ground. The antenna structure is configured to operate as a feeding structure to the parasitic element, the parasitic element not being conductively connected to the antenna structure.
