Abstract :
This paper applies the method of equivalent magnetic current to the field-solve problem of slot antenna which is backed by a single cavity and excited by a waveguide discrete, then it gets the boundary integral equations above the surfaces of the slots .Next uses the method of moment to solve the equations and gets the field structure of the particular antenna. Through using the theory of array antenna, it gets the directivity pattern of the slot array antenna. This directivity pattern is compared to the measured directivity pattern, and gets a nice result.
