Dual band antenna assembly and method for designing the same
First Claim
1. A dual band antenna assembly comprising:
- a baseboard having a first insulating part defined on an upper surface of said baseboard; and
a winding strip section formed in said insulating part and having a heading end and a tail end;
a connected strip section formed in said insulating part and having one connecting end coupled integrally to said tail end of said winding strip section;
a lump-like strip section formed in said insulating part and having a first terminal end serving as a feeding pin and a second terminal end coupled integrally to the other connecting end of said connected strip section;
wherein, a first signal-working band is defined when a first current path flows through said feeding pin and said second terminal end of said lump-like strip section to generate a first resonance, and a second signal-working band is defined when a second current path flows through said lump-like strip section, said first signal-working band being higher than said second signal-working band, said connected strip section and said winding strip section to generate a second resonance.

Abstract
A dual band antenna assembly includes a radiating metal strip fabricated on a baseboard. The radiating metal strip includes a winding strip section having a heading end and a tail end, a connected strip section having one connecting end coupled integrally to the tail end of the winding strip section and the other connecting end, a lump-like strip section having a first terminal end serving as a feeding pin and a second terminal end coupled integrally to the other connecting end of the connected strip section. A first signal-working band is defined when a current path flows through the feeding pin and the second terminal end of the lump-like strip section to generate a first resonance. A second signal-working band is defined when a current path flows through the lump-like strip section, the connected strip section and the winding strip section to generate a second resonance.

11. A method for designing a dual band antenna assembly, comprising the steps of:
-
providing a baseboard; fabricating a lump-like strip section on said baseboard, said lump-like strip section having a first terminal end serving as a feeding pin and a second terminal end, wherein a first resonant path generated due to flow of current through said feeding pin and said second terminal end is defined according to a quarter wavelength of a signal within a first signal-working band for said dual band antenna assembly; fabricating a connected strip section on said baseboard, said connected strip section having one connecting end coupled integrally to said second terminal end of said lump-like strip section; fabricating a winding strip section on said baseboard, said winding strip section having a heading end and a tail end coupled integrally to the other connecting end of said connected strip section; and wherein, said winding strip section, said connected strip section and said lump-like strip section cooperatively define a radiating metal strip for said dual band antenna assembly such that a second resonant path generated due to flow of current through said lump-like strip section, said connected strip section and said winding strip section is defined according to a quarter wavelength of a signal within a second signal-working band for said dual band antenna assembly, said first signal-working band being higher than said second signal-working band. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
