-In the design of the RF antenna for MRI, its size and structure are determined so that they provide desired distribution of electromagnetic field. The moment method using point matching formulation was used for the computation of electromagnetic field due to the antenna and current distribution on the antenna. In order to verify the computation accuracy of the moment method, comparison between computation results and experimental results are performed. In addition, the effect of loading the RF antenna with capacitors to improve the uniformity of the current distribution has been studied.
