Abstract: In order to solve the problems existing in the current antenna for high power microwave weapon,the idea of a magnetized plasma channel used as antenna for radiating electromagnetic pulse is presented.The normal modes of Magnetized Plasma Channel Antenna (MPCA) in lossy gas are analyzed.The concrete realization method of this antenna is simply described.The geometric-model of MPCA is created based on the operating principle of this antenna.The strictest dispersion equation of MPCA is deduced by applying the boundary conditions of electromagnetic fields.Discussion is stressed on the variations of propagation constants with plasma parameters,surrounding material and external magnetic field.The analysis shows that MPCA in a finite magnetic field possesses some different properties compared with a plasma channel antenna where infinite external magnetic field exists.These results are useful for practical application of the antenna.

Key words: MPCA (Magnetized Plasma Channel Antenna), Dispersion Equation, Microwave
