PLANAR INVERTED-F ANTENNA

摘要

A planar inverted-F antenna includes an antenna body including a grounding portion, a first and a second radiating arm extending in a lengthwise direction substantially, a coaxial cable and a metal foil attached the grounding portion. The first radiating arm and the second radiating arm extend in opposite directions from a joint point thereof, the joint point and the grounding portion connect with each other by a connecting portion. A first slot is defined between the first radiating arm and the grounding arm, a second slot is defined between the second radiating arm and the grounding portion. A coaxial cable includes a core soldered to the joint point and a shielding layer soldered to the grounding portion. The metal foil covers a most portion of the grounding portion, thereby exposes a first end of the grounding portion near to the first radiating arm to an exterior.
