Abstract :
A method for calculation of the isolation between radar transmitting and receiving waveguide-fed slot antennas is proposed. The mathematical model of the antenna is based on the antenna decomposition on two separately investigated key-blocks: the antenna array and waveguide divider. The resulting scattering matrix of two antennas is obtained after calculation of the external mutual coupling effects. The practical realization of the model is based on the infinite PEC plane assumption, so it may be used for planar arrays or linear arrays on electrically large bodies.
