INTERNAL ANTENNA UNIT

摘要

PURPOSE: An internal antenna device is provided to reduce radiation power of a first radiator by generation of interference between the electric wave of a second radiator and the first frequency band electric wave radiated from the first radiator. CONSTITUTION: A first radiator(10) radiates the electric wave of the first frequency band and second frequency band. A second radiator(20) radiates the second electric wave along the first electric wave of the first frequency band radiated from the first radiator. The radiation power of the first radiator is reduced by the generation of the interference between the first electric wave and the second electric wave. The frequency of the second electric wave corresponds to the first frequency band. The second radiator radiates the electric wave of a single band.
