摘要：
According to the property of Hertz vector of horizontal electric dipole in stratified biological media, a method is presented by using the Fast Fourier Transform (FFT), by which the complicated Somerfeld integral can be calculated analytically. We have obtained the solution of the Hertz vectors in space domain. The electric field tangential to the microstrip antenna arm is derived by using the relationship between the Hertz vectors and the electric field. In order to get the current distribution of the antenna arm, the moment method is used. It is important to find the current distribution for determining the parameters of antenna and finding the power deposition in biological media.
