1. A multifunctional antenna chip mounted on an electric circuit board provided with a matched circuit for transmitting radio frequency signals, comprising:

  • a packing housing;

    at least a dielectric layer base board provided in said packing housing and having a plurality of via holes;

    an antenna structure at least includes an upper metallic layer and a lower metallic layer respectively allocated on an upper surface and a bottom surface of said dielectric layer base board;

    said upper metallic layer and said lower metallic layer are connected with each other by said via holes to form a folded antenna structure; and

    four connecting pins extended in said dielectric layer base board from four corners of said packing housing to connect said lower metallic layer;

    after passing said matched circuit, radio frequency signals enter said antenna structure via one of a plurality of signal input connecting pins to form a mono-pole antenna, a character thus is provided that said antenna structure being adjusted by said matched circuit to render said antenna structure to have a working frequency meeting communication standard.
