Abstract: Helical protrusion portions are formed on a peripheral side surface face of a bobbin, and a helical element is screwed into the helical grooves formed between the helical protrusion portions. The lower end of the bobbing is screwed onto an attachment fitting provided with a first collar portion at an intermediate portion and a second collar portion at the end. The depth of the helical groove portions becomes gradually shallower toward the leading end of the helical protrusion portions, and the helical protrusion portions formed on the lower end of the bobbin are formed higher, so that the position of the helical element is stabilized. Thus, deviation of the resonance point of the helical element can be prevented.

Abstract: With the object of forming a compact antenna that operates in a plurality of frequency bands, the pattern of an antenna element (14) that can resonate in a plurality of frequency bands is formed on the outer circumferential surface of an antenna bobbin (12). A parasitic conductor (11) is inserted into an accommodating hole, which is formed substantially along the central axis of this antenna bobbin (12). As a result, an antenna that operates favorably in the frequency bands of AMPS, PCS and GPS can be obtained.

Abstract: With the object of providing a mobile wireless equipment with a multi-frequency antenna capable of performing communication with a GPS system in addition to conventional communication with mobile wireless systems, an antenna 10 for mobile wireless equipment and a GPS antenna 4 are tightened together by threading an antenna fixing nut 19 onto a holder 7 from within a casing 101, after inserting a holder 7 of the antenna 10 for mobile wireless equipment from above a through-hole 4b of the GPS antenna 4 and inserting the holder 7, which projects from below, from above into an aperture 101a of the casing 101. Also, positioning and fixing of the GPS antenna 4 are performed by engagement of claws 41, 41 formed on the GPS antenna 4 and a positioning boss 42 with claw receiving sections 43, 43 and a boss receiving section 44 formed in the upper part of the casing 101.
