Abstract: The objective of this paper is to design a parasitic antenna array capable of rejecting interfering signals and directing its main lobe towards the wanted signal. The designed antenna is a linear array consisting of an active monopole and fourteen parasitic monopoles. The method used is LMS, making it possible to calculate the values of the reactive loads to be connected to the ports of the parasitic elements so that the radiation patterns satisfies the fixed constraints. The simulation results in CST-MWS (Computer Simulation Tool Microwave Studio software) of the radiation patterns show an energy level of less than -0.71 dB in the direction of the interference and a gain greater than 5 dB in the direction of the wanted signal. Thus, this technique will make it possible to design directional antennas, with low energy consumption and interference rejection.
