A technique to minimize the effect on resonance frequency due to fabrication errors of MS antenna by operating dielectric constant

Abstract

This paper presents a method to minimize the effect on resonance frequency due to fabrication error of microstrip patch antenna. When a patch antenna is fabricated, dimension of the patch may be slightly differentfrom its calculated value due to error in the fabrication operations, which causes into variation of its resonance frequency. To overcome this problem this paper presents a new technique to minimize the effect on resonance frequency due to fabrication error of MS antenna by operating dielectric constant. Effective dielectric constant of substrate is changed in such a way that the resonant frequency is set back to the calculated value.
