The principles of constructing antenna arrays (AA) and beam formers (BF) for broadband isolation increase between AA are formulated. The values of isolation levels for cosine and exponential amplitude distributions at the BFD outputs of microstrip broadband array antennas of various sizes are given. It is ascertained that the isolation level for arrays of 20λх20λ can achieve the value of not less than -100 dB within the sector of ±600 angles and within the frequency band with the overlap not less than two.
