There is a circuit board having a surface. A first strip conducting part locates at the surface of the circuit board. A first U-type conducting part locates at the surface of the circuit board and connects with the first strip conducting part. A second U-type conducting part locates at the surface of the circuit board and is complementary with the first U-type conducting part. A grounding part locates at the surface of the circuit board and connects with the first strip conducting part. A second strip conducting part connects with the second U-type conducting part and combines the ground part as a micro strip for conducting the antenna signal. Images(3) Claims(5)
[0020] The key components of the diagrams are listed as below: [0021]111: Front Surface of the Circuit Board [0022]13: Grounding Part [0023]141, 142: Strip Conducting Part [0024]211, 212: Surface of the Circuit Board [0025]261: The First U-type Conducting Part [0026]231, 232: The Grounding Part [0027]241, 242: The Third Strip Conducting Part [0028]121, 122: Strip Conducting Part [0029]112: Back Surface of the Circuit Board [0030]15: Conducting Via hole [0031]222, 221: Strip Conducting Part [0032]262: The Second U-type Conducting Part [0033]27: The Second Strip Conducting Part DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0034] FIGS. 2 (A) (B) are the front and back diagrams of the new type circuit board antenna according to the present invention. [0035] There are two surfaces 211 and 212 on the circuit board. We may find the first strip conducting part 222, the first U-type conducting part 261, the second U-type conducting part 262, the grounding part 231, and the second strip conducting part 27 in the surface 211. On this surface, the first U-type conducting part 261 connects with the first strip conducting part 222, and the second U-type conducting part 262 is complementary with the first U-type conducting part 261. Grounding part 23 connects with the first strip conducting part 222, the second strip conducting part 27 connects with the second U-type conducting part 262 and combines with the grounding part 23 as a micro strip for conducting the antenna signal. [0036] Another surface of the circuit board 212 comprises a third strip conducting part 241. The third strip conducting part 241 (or 242) is parallel with the first strip conducting part 221 (or 222) and intercommunicates by multiple conducting via holes 15. Of course, the surface of another circuit board side 212 comprises another grounding part 232, and these two grounding part 231, 232 also intercommunicate by multiple conducting via holes 15. [0037] Furthermore, the first U-type conducting part 261 and the second U-type conducting part 262 will combine as an r(Gama) matching. The new type circuit board antenna of the present invention can be used in a wireless LAN card. Anyway, the quality of the antenna will be improved by the r(Gama) match of the present invention. [0038] While the invention has been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention need not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
