Summary:
In recent years Finite Difference Time Domain (FDTD) method is widely used for printed antenna analysis. Because a complicated-shaped model is easily analyzable by using FDTD method. However, it is well known that quite small cell is required when an extremely accurate result is needed for analyzing impedance characteristics of antennas on dielectric substrate. The improving calculation accuracy method has been proposed for straight shape printed antenna. In the method, quasi-static field was used to improve calculation accuracy. In this paper, we expand the quasi-static approximation to bent antennas including loop antenna and we will demonstrate improvement of calculation accuracy.
