BENT MONOPOLE ANTENNA

摘要

A curved type monopole antenna is provided to raise gain of antenna in small and narrow space inside of a printed circuit board having a part and operate sub pattern part as a similarity parasitic element so that directivity of the antenna emission pattern is improved. A curved type monopole antenna(100) comprises: a printed circuit board in which a RF module generating an electric signal is formed; a feeder(120) which is formed in the printed circuit board in which the RF module is formed and which is connected to the RF module and in which the electric signal is delivered; and a main pattern part(40) which is formed in the printed circuit board and which is connected to the feeder for generating electric field by an electric signal.
