Periscope antenna reradiator based on two coupled arrays

Planar structures reradiating electromagnetic waves are widely used now. Such structures can be seen as planar analogues of reflector antennas. One of perspective variants of their application may be a planar horizontal reradiator of periscope antenna system. The present paper suggests a variant of reradiating structure with longitudinal-broadside reradiation. The suggested structure is simple and manufacturable. Its application as horizontal reradiator for periscope antenna system (PAS) will simplify the design considerably due to load reduction. Periscope antenna systems (PAS), used in radio communication, are large stationary structures. But application of horizontal reradiating array in such structure as reradiator allows simplifying reradiator bearing-lifting gear. At that, basic requirement is capability of reradiator to re-emit power in direction longitudinal to its plane. The second part of the paper introduces PAS reradiator structure on the basis of two coupled antenna arrays. The suggested methods of calculation are supported by experimental investigation of model of the reradiating structure.
