Description
Summary:Using Greenpsilas function in waveguide, the symmetrical dipole antenna integral equation in rectangle tunnel is established. With the method-of-moments (MoM), the radiation modes of symmetrical dipole are analyzed. At last, the TE mode and TM mode electric field strength is presented. Numerical results show that the TE mode and TM mode electric field strength near to the antenna vary little with the frequency or electric conductivity of tunnel wall changing. And the attenuation rate of TE mode electric field strength in far from the antenna is smaller than TM mode at the same condition.
