Abstract
An illuminant-mounted antenna includes a rod-shaped antenna element, an illuminant mounted on top of the rod-shaped antenna element, and lighting means for lighting the illuminant by high frequency energy generated on the rod-shaped antenna element when a portable transceiver is operated. The lighting means includes a high frequency detecting diode and an inductive element. One end of the high frequency detecting diode and one end of the inductive element are connected in common to the top of the rod-shaped antenna element, and the other end of the high frequency detecting diode and the other end of the inductive element are connected to both ends of the illuminant. It is preferable that the rod-shaped antenna element be a whip antenna element capable of transmitting/receiving a very-high-frequency radio wave and an ultra-high-frequency radio wave, and an antenna element mounted on the portable transceiver, the illuminant be a light-emitting diode whose current ranges from 10 mA to 20 mA, and the inductive element be a coil whose inductance ranges from 13 nH to 40 nH.
