We show here the design of a dual beam linearly polarised flat antenna. The main goal is getting a low cost antenna to use for the simultaneous reception of Hispasat and Astra satellite emissions in the 12 GHz band. The gain needed for the antenna is around 30dBi. A rectangular array of slots in the upper side of a parallel plate wave guide form the main antenna structure. The guide is excited with two feeding structures from both sides of the antenna. This antenna has been analized with the TLM Method showed in [1]
