The paper proposes an economical, small size and compact fractal Koch dipole antenna for its resonance within 4 –5 GHz frequency band. The antenna and its array have been bent to calculate and show the parametric behavior with its curvature. The reflection parameter and its gain within the frequency band has also been calculated and compared with open end, short end and its bend configuration. A trained neural network function has been used to calculate antenna parameters of the array antenna using the known parameters of single element antenna. In addition the paper also provides frequency dependent impedance plot using ADS tool and its matching circuit for its application within controlled impedance PCB environment.
