Estimating the term…
A wireless electronic device includes an inverted-F antenna (IFA) having an IFA exciting element, an IFA feed, and a grounding pin. The IFA exciting element is configured to resonate at two different resonant frequencies, when excited by a signal received through the IFA feed. The wireless electronic device includes a highband wave trap having a length defined based on a first resonant frequency of the IFA exciting element. The highband wave trap is electrically coupled to the IFA exciting element through the grounding pin. A ground patch is electrically coupled between the highband wave trap and the ground plane. The wireless electronic device includes a lowband wave trap having a length defined based on a second resonant frequency of the IFA exciting element. The lowband wave trap is electrically coupled to the ground plane through the ground patch.
