PLANAR INVERTED F ANTENNA

The present invention relates to a plate-like reverse-F antenna. The plate-like reverse-F antenna according to the present invention includes: a ground surface made of a conductor; an antenna body which has a part interconnected with a power feed point and transmits or receives radio waves; a short-circuit pin which makes an end of the antenna body come in contact with the ground surface; and a tuner chip which is connected to the other end of the antenna body and maintains the frequency band of the radio waves exchanged through the antenna body to be within a predetermined range. The present invention can implement an ultra-small antenna with short antenna body by using the tuner chip. More specifically, the length of the antenna is reduced and is easily installed in a tiny space.
