<p><P>PROBLEM TO BE SOLVED: To provide a switch/antenna, a pulse generator and an associated apparatus which are suitable for an impulse type communication device capable of reducing a power consumption. <P>SOLUTION: At standby time, a first switch S1 is turned on, a second switch S2 is turned off, and a resonance circuit 14 and an antenna 12 are charged. At transmission time, the first switch S1 is turned off, and the second switch S2 is turned on. A signal of a resonance frequency of the resonance circuit 14 is reflected in the resonance circuit, residual in the antenna 12 and radiated soon in the air as a radio wave. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
