Abstract

An improved inverted-F antenna, adapted for wireless communication devices, is disclosed, which comprises: a ground plane; a pin, coupled to a side of the ground plane while extending vertically upward therefrom; a first radiation unit, connected to an end of the pin that is not connected to the ground plane while enabling the periphery of the same to align with the periphery of the ground plane. Moreover, the inverted-F antenna is further comprised of: a second radiation unit, connected to the end of the first radiation unit that is not connected to the pin while enabling the same to be enveloped within the periphery of the ground plane, and being shaped like a fan tapering toward the end thereof that is connected to the first radiation unit; and a feed point, disposed extendingly from an end of the first radiation unit for feeding electrical signals.

First claim

What is claimed is:

1. An improved inverted-F antenna, being adapted for wireless communication devices, comprising:
a ground plane;
a pin, wherein one end of the pin is coupled to a side of the ground plane while extending vertically upward therefrom;
a first radiation unit, being of a U shaped structure and connected to the other end of the pin and there is a space formed between the first radiation unit and the ground plane, and the first radiation unit's projection on a pl…
