Abstract:
    Under precondition without changing size of external diameter, the invention discloses integrated antenna on chip. The helix structural antenna possesses gradual changed widths of metal coils and spans of metal coils in order to reduce serial equivalent resistance of helix coils so as to reduce energy loss. Comparing with traditional antenna on chip, the disclosed antenna on chip possesses features of lowering influence of eddy current effect and approach effect in high frequency so as to reduce the said equivalent resistance Rs, and energy loss. The preparing technique is compatible to conventional CMOS technique.
