Abstract

Accurate MWM-based closed-form expressions are presented to determine total lumped capacitance C₁ and effective radius R_eff of a microstrip circular patch in the range 0.1 ≤ h / R ≤ 10 and ∈_r ≤ 1, with maximum errors of 5% and 2.5% for C_t and R_eff, respectively, on ∈_r = 1. The results are compared to those obtained with Noble's variational method. For ∈_r > 1, the error of the present model decreases. A graphical method is also presented to determine the R_eff of the circular patch, which has an accuracy of < 1.5% versus the calculated value.
