摘要： PROBLEM TO BE SOLVED: To provide the antenna mounted with a light emitting body provided with a lighting means surely and stably lighting a light emitting body mounted on a top of a rod antenna element in which a comparatively a high detection voltage is obtained even when a high frequency energy on the rod antenna element is weak. SOLUTION: The antenna 3 mounted with a light emitting body is formed by mounting a light emitting body 23 at a top of a rod antenna element 10 and lighting the light emitting body 23 with a high frequency energy on the rod antenna element 10 in the operation of a transmitter-receiver 1. Each one end of a high frequency detection diode 31 and an inductive element 32 at the top of the rod antenna element 10 is connected in common and the light emitting body 23 is connected between the other end of the high frequency detection diode 31 and the other end of the inductive element 32.

摘要： PURPOSE:To provide the ultrashort wave antenna for radio telephone set which reduces straight capacity to a ground, decreases the loss of radiated energy, facilitates impedance matching, obtains a wide band characteristic, sufficiently displays a function as a transmission/reception antenna, is rich in durability at an element supporting part, stably keeps an element holding angle for a long time and further is equipped with a rotation diffracting mechanism produced small. CONSTITUTION:A columnar supporting base 14 and a holder 11 or the like of the rotation diffracting mechanism interposed in the fitting part of an antenna element 1 are formed by resin, the antenna element 1 is set and held at the prescribed angle by an element angle setting means 30 composed of a ball 16 and a coil spring 17 or the like, and recessed and projecting elastic contact parts are peripherally arranged while being faced each other on the outer peripheral face of the columnar supporting base 14 and the inner peripheral face of the resin holder 11 so as to intermittently turnably hold the resin columnar supporting base 14 in the resin holder 11.

摘要： PURPOSE:To prevent the damage on a feeding cable and reduction in antenna characteristics and to attain excellent communication by allowing a cable of which one end is fixed to the base end of an antenna body and the other end is connected to the I/O terminal part of a radio communication set to pass through rotation side and connection side cylindrical hollow parts. CONSTITUTION:A radio communication antenna supporting device is provided with a fixed side connecting cylindrical body 10 having a fixing flange 11 to be fixed to the casing of the radio communication set on its outer peripheral part, a rotation side connecting cylindrical body 20 having a shaft cylinder 21 to be rotatably engaged with the inside of the cylindrical body 10 at its base end part and an antenna body mounting part 22 to its tip part and a rotation regulator 30 for regulating the rotation range of the cylindrical body 20 to the cylindrical body 10. Thereby a feeding cable 2 of which one end is fixed to the base end part of the antenna body 1 mounted to the mounting part 22 and the other end is connected to the I/O terminal of the radio communication set is passed through the hollow parts of the cylindrical bodies 20, 10 in a freely inserted state. Consequently the cable 2 can be avoided from being extremely bent or sharply twisted.
