In this article, a concise equivalent circuit model for top‐loaded folded monopole antenna (TLFMA) of low profile is presented. The TLFMA has one driven post and one shorting post, loaded with a circular conducting plate on the top, which can achieve a very low profile with a good radiation resistance. The equivalent circuit consists of two models, which are transmission‐line mode and antenna mode. The impedance of TLFMMA can be easily get from this equivalent circuit model. The accuracy of the presented equivalent circuit model has been verified by the simulation and measurement results.
