Now-a-days, low profile passive array antennas are being more and more used substituting traditional parabolic antennas in satellite communications. To achieve a good efficiency in printed arrays it is necessary to use a low loss network. A shielded suspended stripline is proposed in this paper. The main aim of this network is to distribute the power among subarrays in an array antenna with minimum losses. Several vertical transitions to subarrays are shown besides some network designs for square arrays at X band.
