The paper is focused on a formulation of a new coefficient of the low-pass prototype filter for the design of a four-element filtering antenna array. Due to the new gicoefficients, we can comfortably and easily control a shape of the frequency responses of the reflection coefficient and normalized realized gain. The described process of the design methodology and new gicoefficients were verified over the frequency band from 4.8 GHz to 6.8 GHz; for fractional bandwidth from 8 % to 12 % and for level of the reflection coefficient from -10 dB to -20 dB. The whole design methodology was supported by comparison of three samples of filtering antenna arrays with different configuration.
