In this study, a modified curve fitting model (CFM) for cylindrical dielectric resonator antenna (DRA) exclusively using YIG resonator with excess Fe 2 O 3 is proposed. The modified CFM is used to accelerate the analysis of YIG resonator antenna (YRA) without having to repeat the characterization process for similar resonator. Modification of CFM is done using least square method in which correlation and regression analyses are used. The modified equations of resonant frequency and Q‐factor are adapted for the YRA design using YIG resonator with excess Fe 2 O 3 of 9%. Comparison between the simulation, measurement, and modified CFM results are very well matched.
