MULTI-FREQUENCY ANTENNA

摘要

A multi-frequency antenna capable of performing communication with a cellular radio system and the GPS system in a cellular radio device. A holder portion (7) of a cellular radio device antenna (10) is inserted from above of a through hole (4b) of a GPS antenna (4). The holder portion (7) protruding downward is inserted from above of an opening (101a) of a casing (101). The cellular radio device antenna (10) and the GPS antenna (4) are screwed to the holder portion (7) by an antenna fixing nut (19) from inside the casing (101). Moreover, claws (41, 41) and a positioning boss (42) formed on the GPS antenna are engaged with claw receivers (43, 43) and a boss receiver (44) formed on the casing (101), thereby positioning and fixing the GPS antenna (4).
