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.
