摘要 |
<p>An antenna device (A3) for a portable telephone includes a whip antenna (1) having a larger-diameter portion (52) formed near its upper end by means of forming. The guide ring (7) consisting essentially of a synthetic resin fits on the whip antenna (1), such that the guide ring (7) abuts against the larger-diameter portion (52) to rest at a position below the larger-diameter portion. The whip antenna (1) and the guide ring (7) are coated with a coating layer (19) consisting essentially of a synthetic resin. The coating layer (19) has a main portion (54) coating the whip antenna (1) below the guide ring (7), and a joint portion (56) coating the guide ring (7) and the larger-diameter portion (52). A helical antenna (25) is arranged such that it is electrically connected to a metal terminal (62) and is mechanically connected to the whip antenna (1) through the joint portion (56) and the metal terminal (62). The helical antenna (25) is coated with a block (31) consisting essentially of a synthetic resin. <IMAGE></p> |
