CAD of Chebyshev-type microstrip feeding structure of linear antenna array

Abstract

The results of the modeling of electrical behavior of Chebyshev-type feeding structure, fabricated in integrated microstrip line based technology have been presented and concluded. Analytical results have been verified experimentally of considered structure fabricated on RT-Duroid substrate material with thickness h=1.27 mm and electric permittivity /spl epsi//sub r/=10.2 at midband frequency F=1.06 GHz. The achievements of this study demonstrate the accuracy of applied simulation tools as well as the potential utility of analyzed structure as multielement antenna feeder.
