An antenna system for portable radio equipment is composed of first and second antenna portions (19, 20). The first antenna portion (19) has a loading section (21) and is provided at a position projected from a casing even when the antenna system is retracted and is also coupled to a power-feeding portion (12). The second antenna portion (20) is connected to a lower end of the first antenna portion (19) to be containable in the casing, and is coupled to the power supply via stopper (8) at the base end portion when the antenna is extended. The second antenna portion (20) is electrically insulated from the first antenna portion (19). Since the first and the second antenna portions (19, 20) are electrically insulated from each other, no power-feeding to the contained portion will take place when the antenna is retracted. Modified antenna portions are disclosed employing strip conductors. <IMAGE> |
