MULTIFUNCTIONAL ANTENNA CHIP
First Claim
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.

Abstract
A multifunctional antenna chip is able to mate with many kinds of matched circuits and is able to adjust the character of an antenna structure of the multifunctional antenna chip, in order that the antenna structure has one or multiple standard working frequencies. The antenna structure is a folded antenna structure basically; this can save its volume occupied. And the multifunctional antenna chip has a non-signal inputting pin for connection to thereby increase shape of the antenna for adjusting the style of the antenna structure designed.
