The paper considers the use of microstrip filters in the construction of an adaptive antenna array. The technique for calculating the parameters of filters for given values of central frequency, bandwidth and depth of the barrier bars has been given. The method for increasing the steepness of the slopes of the amplitude-frequency characteristic of band-pass filters has been developed, by forming the additional coupling between non-neighboring resonators. The filter design has been proposed for use in an adaptive antenna array low-noise amplifier.
