Patent ID: 7199757

Claim:
An antenna assembly comprising: a base board defining a grounding domain and a dielectric domain; a ground metal layer fabricated on said grounding domain in said base board; a dielectric medium, being a perspective structure, mounted on said dielectric domain in said base board, and having an upper surface and at least one lateral surface; a first metal strip including a wave-like strip section mounted on said upper surface of said dielectric medium, a feed-in end, and a lateral strip section mounted on one of the at least one lateral surface of said dielectric medium, said lateral strip section having a first open end, the lateral strip section being connected to one end of the wave-like strip section, the feed-in end being connected to another end of the wave-like strip section; and a second metal strip fabricated on another one of the at least one lateral surface of said dielectric medium, said second metal strip having a coupling end coupled electrically to said ground metal layer, and a second open end; whereby, after assembly, said first and second metal strips and said ground metal layer cooperatively form an oscillator by virtue of electromagnetic induction to possess a specific frequency range, thereby permitting transmitting and receiving data signals under multi frequencies within said specific frequency range.
