Performance of Thinned Microstrip Reflectarrays

M. Wasif Niaz, Zubair Ahmed and Mojeeb Bin Ihsan

Abstract—A reflectarray uses the phasing characteristics of microstrip patches, on its aperture, to direct the main beam in a desired direction. The geometry and dimensions of the microstrip patches are used to control these phasing characteristics. Normally grid arrangement of microstrip patches on reflectarray aperture is rectangular or circular grid. In order to reduce the number of microstrip patched on reflectarray aperture, a novel thinning concept is proposed here. This thinning of reflectarray is proposed in the form of a novel windmill shaped grid setting. Parameters such as gain, SLL, beamwidth and number of elements of this reflectarray are compared with reflectarray having conventional grid settings and are presented in this paper.
