发明名称 ANTENNA AND COMMUNICATION APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide an antenna which has good characteristics and contributes to reduction of the size and the thickness, and to provide a communication apparatus using the antenna. <P>SOLUTION: An antenna includes an antenna substrate 21 and a dielectric member 20 and is disposed on an inner surface of a housing of a communication device so as to have a gap with a plate surface of a printed circuit board 3 forming the communication device. The dielectric member 20 is provided on a plate surface of the antenna substrate 21 which faces an inner surface 10a of the housing 10. This structure eliminates the need for a space for disposing a dielectric body on the printed circuit board 3 and obtains effective wavelength shortening effect with the dielectric member 20 provided on the plate surface of the antenna substrate 21. Therefore, the reduction of the size and the thickness of the communication device is achieved. <P>COPYRIGHT: (C)2013,JPO&INPIT
