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.
