Radiation Device for Planar Inverted F Antenna and Planar Inverted F Antenna using it

摘要

PURPOSE: A planar type inverse-F antenna radiator and a planar type inverse-F antenna using the same are provided to obtain a broadband characteristic by forming the radiator having an edge of a taper shape. CONSTITUTION: A planar type inverse-F antenna using a planar type inverse-F antenna radiator includes a grounding part(107), a disconnecting part(103), a feeding part(105), and a radiator(201). The grounding part is used for connecting the radiator(201) to the ground. The disconnecting part(103) is used for disconnecting the radiator. The feeding part(105) is used for feeding the current to the radiator(201). The radiator(201) is used for radiating the current of the feeding part(105). The radiator has a taper shape. The length and the width of an end part of the radiator are decided by a resonant frequency.
