Abstract
The antenna miniaturization technique involves the increment of the electrical length of the resonator the variation of the physical appearance of the antenna. The most typical method of size reduction is designing helical antenna, meander antenna, and fractal antenna. Size reduction using fractal antenna is proposed in this paper. Fractal koch curve has been etched in microstrip patch antenna to downsize the antenna at ISM (Industrial Scientific and Medical) frequency band of 2.45 GHz koch curve microstrip patch antenna ha FR4 epoxy substrate with dielectric constant 4.7, loss tangent equal to 0.02 and dielectric high of 1.6 mm. The designed antenna is fabricated using etching process. The fabricated antenna has return loss of 2.45 GHz, VSWR of 1.1492, and impedance is matched to $46{\Omega}$.
