ANTENNA

摘要

PURPOSE: An antenna is provided to reduce reflection loss by forming a stub between a feeder conductive pattern and a radiator. CONSTITUTION: A radiator(120) is formed in one side of a dielectric substrate(110). The radiator has a UWB(Ultra Wide Band) frequency band characteristic and is formed with a patch type. A feeder conductive pattern is formed in the center of one side of the dielectric substrate. One side of the feeder conductive pattern is connected to the radiator. The other side of the feeder conductive pattern is connected to the outer feeder line. A first slot(140) is formed in the feeder conductive pattern. The first slot divides the feeder conductive pattern into the plural parts. A ground surface(150) is formed in the other side of the dielectric substrate. A second slot(160) is formed on the ground surface.
