Abstract
Multiple helical coils (110, 120, 130) are placed side-by-side and coupled to a conductive straight portion (140) of an antenna to provide a multi-band antenna structure. The helical coils (110, 120, 130) are distanced from one another to sufficiently eliminate coupling interference therebetween. A portable radio capable of communication in many different frequency bands utilizing a single, compact antenna structure is thus realized.
