| Abstract: | The present status of theoretical research on leaky coaxial cables is summerized. Focussing on operation frequency-band and coupling loss the design method for radiation leaky coaxial cables is discussed. Based on the analysis of spatial harmonics of periodically slotted structure the method for extending operation frequency-band through suppressing higher-order harmonics is discussed. And the finite-difference time-domain approach and Matlab software are used to calculate the coupling loss of the cables. |

| Keywords: | leaky coaxial cable spatial harmonic surface-wave suppression of the high-order harmonics coupling loss FDTD |
