The antenna device

The present invention provides an antenna apparatus, the antenna device may be loaded into a mobile radio telephone set main body of the machine, or may be drawn from the telephone body can be avoided when the antenna characteristics deteriorate revenue telephone body, while shortening the length of the vibrator and increase its strength. Said antenna means, by a helical antenna operating income when the radio unit main body, and the whip antenna is pulled out from the radio operating unit main body constituting the helical antenna and the whip antenna is electrically insulated from the whip antenna through the helical antenna. Preferably, the helical antenna having a connection portion connected to the radio circuitry in the main body of radio revenue, the whip antenna disposed close to said connecting portion, and having a first portion connected to the ground when the body radios income , and withdrawn from the radio unit main body connected to the radio circuitry of the second connecting portion.
