Six-channel broadband inhomogeneous microstrip power divider for communication antenna array

Problems of the design and computer simulation of inhomogeneous microstrip power divider for octave L-S frequency band for the base station antenna array of the radiocommunication system are considered in this paper. Broadband matching of the antenna array and synthesis of the optimal matching networks are discussed. Theory base of mathematical analysis of the broadband multiport divider, microstrip realization and results of computer analysis and experimental investigations are presented. Influence of some possible mismatching of the real microwave array on signal antenna distribution is discussed.
