Patent ID: 8269681

Claim:
A sheet-like dipole antenna, mounted within an electronic product and including: a substrate ( 1 ) having a copper clad surface ( 11 ), the copper clad surface ( 11 ) having a slot ( 12 ) constituted of a short-strip section ( 12 a ), a rectangular section ( 12 b ), and a long-strip section ( 12 c ), an insulating film ( 13 ) being provided on the copper clad surface ( 11 ) and the slot ( 12 ), a rectangular first soldering region ( 14 ) uncovered by the insulating film ( 13 ) being formed on the copper clad surface ( 11 ) in front and rear of the rectangular section ( 12 b ) of the slot ( 12 ) respectively, a squared second soldering region ( 15 ) uncovered by the insulating film ( 13 ) being formed on the copper clad surface ( 11 ) to connect to one side of the first soldering region ( 14 ), one side of the second soldering region ( 15 ) being connected to the long-strip section ( 12 c ) of the slot ( 12 ), a squared third soldering region ( 16 ) uncovered by the insulating film ( 13 ) being formed on the copper clad surface ( 11 ) to connect to the other side of the long-strip section ( 12 c ) of the slot ( 12 ); and an F-shape antenna ( 2 ) having a carrier ( 21 ), a top surface of the carrier ( 21 ) having a radiation metallic surface ( 22 ), the radiation metallic surface ( 22 ) having an input pin ( 23 ) and a grounding short-circuit pin ( 24 ) extending to one side of the carrier ( 21 ), the F-shape antenna ( 2 ) being soldered to both of the first soldering regions ( 14 ) with the input pin ( 23 ) electrically connected to the second soldering region ( 15 ).
