Abstract :
Strong couplings characterizing wide-band arrays lead to a wide variation of the active element patterns in finite arrays. We show how finite-by-infinite array simulation results and infinite-array solutions can be combined to estimate the element patterns in arrays finite in both directions. The accuracy of the method is discussed for the case of dual-polarized arrays of tapered-slot antennas, with electrically interconnected elements. For elements located in the array corners, a second correction procedure, based on results obtained for small arrays, is presented.
