i was wondering if anyone can help me figure out how to calculate the nulls, minors, majors and grating lobes of an antenna array in matlab? i have tried several times but i really cant get anything to work. 9
Display the array pattern. pattern(array,fc,'ElementWeights',ones(16,8)); Compute the number of elements and the number of subarrays. getNumElements(array) ans = 128 getNumSubarrays(array) ans = 8 Then get the subarray positions.

This program is written in MATLAB as it is used by most institutions. The program utilizes a Graphical User Interface (GUI) to visualize the array developed. Then the program may also be utilized to call antenna simulation software, such as free simulation software, Numerical Electromagnetics Code...
