摘要

The paper analyzes the circular loop antenna based on the theory of Maxwellian circuits, and the current distributions of the antenna are obtained. Results are verified by moment methods, the good agreements prove the efficiency and correctness of the analysis in the paper. Through closer investigation on the second order MC equation, we deduce the current's analytical formula of the circular loop antenna. The formula suits to compute the circular loop antenna of any size. The results of the paper have certain reference significance to more complicated electromagnetic structures.
