In this paper we present a conception and design of microwave circuit based on liquid crystal. The conception will be made of a manner to have a device that functions with a dual frequency and dual polarization. The goal of the dual frequency and dual polarization is to provide a multi-dimensional picture of meteorological phenomena to get more complete data of survey climatic long term and also for the use precipitation of the pictures in the radars. The whole system required in the broadcasts of space as in satellite imaging systems.The liquid crystal polymer has unique features: electric, mechanical, chemical; its extremely flexible nature and the capacity to be laminated with a low cost and a lightweight, to return an appropriate substrate for the big applications of the multilayer antennas.
