The design of a uniform rectangular array for antenna directivity at an operating frequency of 3GHz. The array is designed for three different cases, with varying element spacing and grid angles. the necessary calculations and parameters for each case, as well as the directivity of the array. The document also includes plots of the array's patterns and directivity.
