Abstract

The method of designing microstrip array antenna for low sidelobe level and narrow beam-width using Dolph-Chebyshev array is presented. The widths of microstrip antenna corresponding to excitation coefficients obtained by Dolph-Chebyshev array polynomials is decided by calculating radiation resistance using cavity model analysis. The cascaded array microstrip antenna composed of 10-elements with resonant frequency to be 9.43[GHz] is fabricated by using design method presented in this paper. The experimental results of relatively good characteristics show that its gain, sidelobe level and beam-width are 9[dB], -22[dB] and 8.7[$^{\circ}$].
