发明名称 ANTENNA UNIT AND COMMUNICATION APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To realize a communication apparatus having satisfactory communication characteristics by making an antenna unit to be shared in a plurality of frequencies small in size and broad in band. <P>SOLUTION: The antenna unit is provided with an inverted F-shaped antenna element with a feeding point and a ground connection point and a parasitic antenna element provided in order to resonate with the inverted F-shaped antenna element by electrostatic coupling. The antenna unit may further provided with a ground part grounded to a ground and connected with the ground connection point provided to one end of the Inverted F-shaped antenna element and a resonant element one end part of which is connected with the ground part and which is resonated by the parasitic antenna element by the electrostatic coupling. <P>COPYRIGHT: (C)2004,JPO&NCIPI
