PRINTED CIRCUIT TECHNOLOGY MULTILAYER PLANAR REFLECTOR AND METHOD FOR THE DESIGN THEREOF

摘要

The invention relates to a printed circuit technology multilayer planar reflector reflecting the electromagnetic field from a feeder forming a collimated or conformal beam by performing fine adjustment of reflection phase coefficient. Phase control is effected by adjusting the dimensions in each element that is formed by several layers of conductive patches, spacers and conductor plane. The inclusion of two or more layers reduces sensitivity to manufacturing tolerance and improves the width of the reflector band. The invention also relates to a design method for obtaining photomasks involving the following steps: a) defining the phase difference in each element; b) adjusting the dimensions of each element to the central frequency; c) performing fine adjustment to meet specifications. The reflector according to the invention can be used as antenna for terrestrial and satellite communications, collapsible antenna and conformal beam reflector.
