ABSTRACT:
Disclosed herein is a subminiature internal antenna, which exhibits a multi-band characteristic. The internal antenna includes a radiator electrically coupled at one end thereof to a feed element of a communication device and formed in a spiral shape as a whole. The radiator is disposed in such a manner as to extend at the other end thereof outwardly from the spiral shape. According to the present invention, the electromagnetic coupling is achieved in the radiator of the internal antenna and the other end of the radiator is disposed outwardly from the spiral shape so that the radiation interference is reduced to thereby obtain the multi-band characteristic.
