Dual-frequency inverted-F antenna

摘要

A dual-frequency inverted-F antenna (PIFA) (1) for an electronic device has a ground plane (13), a first radiating patch (11) parallel to the ground plane, a second radiating patch (12) parallel to the first radiating patch, and a first and second connecting portions (111, 121) respectively connecting the first and second radiating patches with the ground plane. The first radiating patch and the ground plane constitute a first frequency resonant structure, and the first and second radiating patches constitute a second frequency resonant structure.
