TUNABLE ANTENNA STRUCTURE

摘要

Example embodiments disclosed herein relate to a tunable antenna structure. A short arm of an antenna structure is coupled to a matching circuit, where the matching circuit is coupled to an input signal. A long arm of the antenna structure is coupled to at least one active tuning element. The short arm is for tuning the antenna structure to a high frequency band and the long arm is for tuning the antenna structure to a low frequency band.
