• In this paper, a method of feeding point analysis is proposed for microstrip antenna that is based on the probe current compensation (PCC) method and the overlapping-grid technique (OGT) in FDTD. Generally, in the Maxwell and Ampere's differential curl equation-based FDTD, calculated error occurs in computation of the feeding point current. By applying the PCC method, the current of the feeding point can be compensated. This paper also analyzes the proposed feeding point model with cylindrical shape. When feeding point model is analyzed by rectangular coordinate, contour path error occurs. Therefore, the OGT is proposed to solve the contour path error. In the OGT, the cylindrical coordinate is applied for modeling of feeding point. In the case of using the PCC method and the OGT, the calculated error and contour path error are reduced and improved.
