An antenna and a manufacturing method thereof are provided to form an antenna pattern by previously forming an ABS(Acrylonitrile Butadiene Styrene) layer on a PC(Poly Carbonate) or PVC(Poly Vinyl Chloride) substrate through printing or coating according to a design shape of the antenna pattern. A manufacturing method of an antenna includes the steps of: preparing a printing compound for a pattern guide used as a guide of an antenna pattern by mixing ABS resin with thinner in a volume ratio of 1:1 to 7:3(S1); forming a pattern guide layer by printing or coating the printing compound on a PC or PVC substrate according to a design shape of the antenna pattern(S2); drying the substrate with the pattern guide layer at a normal temperature or in a thermal dryer(S3); performing ultrasonic degreasing of the substrate(S4); forming unevenness on a surface of the substrate by impregnating the substrate with a mixed solution of chromium anhydride and sulphuric acid to extract a rubber component from the pattern guide layer(S5); adsorbing and permeating metal ions into the unevenness of the pattern guide layer by impregnating the etched substrate with a mixed solution of metal ions and hydrochloric acid(S6); smoothing a surface of the pattern guide layer by impregnating the substrate with a sulphuric acid solution(S7); forming a conductive coating film on the surface of the pattern guide layer by performing chemical plating on the substrate(S8); forming a conductive copper pattern layer on the conductive coating film by performing electro or electroless plating on the substrate(S9); forming a nickel metal layer on the copper pattern layer by performing the electro or electroless plating on the substrate again(S10); forming a guide hole on the substrate by performing primary piercing punching along a printing pattern on the substrate(S11); and completely separating the entire product including the copper pattern layer from the substrate by performing secondary blanking punching through the second guide hole(S12).
