Collapsable Portable Wireless Unit

摘要

A collapsable portable wireless unit ( 100 ) comprises an upper case ( 101 ) and a lower case ( 102 ) coupled through a hinge member ( 103 ) to open/close freely. A planar conductor ( 105 ) is arranged on the upper case ( 101 ). First and second power supply sections ( 111, 112, 103 ) are arranged on the planar conductor ( 105 ) at a specified interval. A harmonic signal distributor ( 120 ) is arranged on a circuit board ( 110 ) provided in the lower case ( 102 ) and distributes a harmonic signal to the first and second power supply sections ( 111, 112, 103 ). A phase shifter ( 121 ) sets the exciting phase of the harmonic signal in the second power supply sections ( 112, 103 ) at a value different from that of the exciting phase of the harmonic signal in the first power supply sections ( 111, 103 ).
