Abstract

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.

Description

technical field [0001] The inventive concept relates generally to the field of wireless communications, and more particularly, to antennas for wireless communications devices. [0002] Cross References to Related Applications [0003] This application claims priority to US Patent Application No. 14 / 595,267, filed January 13, 2015, the entire disclosure of which is hereby incorporated by reference. Background technique [0004] Wireless communication devices, such as cellular telephones and other user equipment, may include antennas that may be used to communicate with external devices. These antennas can produce different types of radiation patterns in the vicinity of the communication device. However, some antenna designs can contribute to undesired amounts of ground currents and irregular radiation patterns. Contents of the invention [0005] Various embodiments of the inventive concept include a wireless electronic device having an inverted-F antenna (IFA). The IFA ...
