A Study on Resonance Frequency Accuracy of Microstrip Patch Antenna Design with Inset-Feed Structure

Abstract

To minimize the resonance frequency error when design Inset-Fed Microstrip Patch Antenna using current formulas. Especially It is found that a constant relation between Antenna patch width and frequency error. Using this relation, calculation frequency and simulation frequency are compared. Finally the comparison induced a formula of revised antenna patch width for accurate frequency in 2-10 GHz. And this formula reduced 2.54% of average frequency error. Last, the Antenna which has same variation with the simulation was producted and measured. It proved the formula's validity.
