Abstract
A structure of a helix antenna, wherein a non-uniform helical coil is press positioned between an inner insulating sleeve and an external insulating sleeve slipping one over the other, the coil is abutted respectively against the inner top surface of the external insulating sleeve and a metallic connecting seat of the inner insulating sleeve. A metallic contact piece is abutted against the metallic connecting seat, has a continuous bending portion exposed from a side slit on the inner insulating sleeve, and has a bottom end for press contacting an RF electric circuit of a communication instrument. The coil has on the top end a diametrically extending bent section to be an added loading of the antenna, the bottom end of the coil has a denser coil section positioned on the surface of the metallic connecting seat. The inner and external insulating sleeves have an external protruding annulus engaged with an inner annular recess for assembling the helical coil to have a fixed length.
