<p>A rear case (13) of those that compose a cellular phone includes part of a case body (10) and an antenna mount (11). An antenna (2) for transmitting and receiving radio waves for satellite communications comprises a cylindrical driver element (20) and a cylindrical helical antenna (21). The helical antenna (21) can be extended in the driver element (20) while it is isolated from the driver element. The driver element (20) is formed integrally with the rear case (13) so that the inside (25) of the antenna mount (11) may make close contact with that part (30) of the outer surface of the driver element (20) where an antenna element (32) is formed. Therefore, the procedure of attaching fixtures to the case is eliminated, and this provides a simplified process of manufacturing.</p> |
