BENT MONOPOLE ANTENNA

摘要

A curved type monopole antenna is provided to replace an existing helical antenna effectively and raise gain of an antenna in small/narrow space inside of a printed circuit board having a part. A curved type monopole antenna comprises a printed circuit board, RF module and feeder. The RF module is installed at the printed circuit board and generates an electric signal. The feeder(120) in which the electric signal is delivered is connected to the RF module. As to a patterned portion for generating electric field with the electric signal which is connected to the feeder and is applied, a main pattern part(40) and sub pattern part(130) are formed. The main pattern part is formed in order to have a via pattern formed through the printed circuit board.
