A center-feed waveguide transverse slot linear array using a transverse-slot feed for blocking reduction

The authors have proposed a center-feed waveguide transverse slot linear array using a transverse slot feed. The blocking width can be reduced by the transverse slot feed than the longitudinal one. The relative bandwidth of the center-feed array is increased to be 3.9% from that of the end-feed array, 2.34%. Stable main beam direction is also realized in the center-feed array.
