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).
