DUAL-BAND INVERTED-F ANTENNA WITH MULTIPLE WAVE TRAPS FOR WIRELESS ELECTRONIC DEVICES |
摘要 |
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. |

1. A wireless electronic device comprising:
an inverted-F antenna (IFA) comprising an IFA exciting element, an IFA feed, and a grounding pin, wherein the IFA exciting element is configured to resonate at both a first resonant frequency and a second resonant frequency, different from the first resonant frequency, when excited by a signal received through the IFA feed; a highband wave trap having a length defined based on the first resonant frequency of the IFA exciting element, wherein the highband wave trap is electrically coupled to the IFA exciting element through the grounding pin; a ground patch that is electrically coupled between the highband wave trap and a ground plane; and a lowband wave trap having a length defined based on the second resonant frequency of the IFA exciting element, wherein the lowband wave trap is electrically coupled to the ground plane through the ground patch. |
