ABSTRACT:
An antenna body of a broadband inverted-F antenna is printed on a circuit board, wherein an interval is maintained between the antenna body and a grounding plane disposed at a position proximate to an edge of the circuit board. The antenna body is divided into a first, a second and a third portions. An end of the first portion is extended towards the grounding plane to form the short circuit line, and another end of the first portion is extended towards the grounding plane to form the feed line. A first end of the second portion is connected to another end of the first portion, a second end of the second portion is connected to an end of the third portion, and the first portion has a wire width smaller than the third portion, so that no metal is existing between the second and third portions and the grounding plane.
