Experimental Results of a New Method on Lessening The Grating Lobes' Effects in Phased Arrays

To design a phased array antenna, different criteria should be considered. Nulls must be placed toward the interferes' directions and the main beam should be focused on the desired user. To accomplish these conditions, several methods can be used. What is important in this paper is how additional roots can be added into AF
