Abstract—In this study, a dual-band rectangular microstrip antenna is designed for mobile cellular 1.815 GHz and WLAN 2.45 GHz applications by combining the Method of Moments (MOM) based simulation (IE3D) and frequency-dependent Smith-Chart model. The frequency-dependent Smith-Chart model is adopted in this research to reduce an error due to effects of the frequency-dependent characteristics. Considering effects of very high operating frequency in GHz frequency range, frequency-dependent characteristics need to be considered to reduce the calculation error in the design. Specifically, the frequency-dependent characteristic impedance is addressed in length in the algorithm so possibility of errors is mitigated in very high frequencies. The method adopted in this paper can be applied in CAD applications with fast and user-friendly implementations.

Index Terms—Frequency-dependent, smith-chart, microstrip, dual band, computer aided design (CAD).
