Abstract :
We show the design of a linearly polarised flat antenna. The main goal is getting a low cost antenna to use for the reception of Hispasat satellite emissions in the 12 GHz band. The gain needed for the antenna is around 30 dBi. A rectangular array of slots in the upper side of a parallel plate waveguide form the main antenna structure. The guide is excited by one planar feeding structure consisting of an array of rectangular microstrip patches. We also modify the feeding network the design procedure and the materials used to build of the radiation surface.
