Abstract :
Scan blindness phenomenon is studied for finite phased arrays of printed dipoles on grounded planar dielectric slabs. A new method for predicting the scan blindness angles using the average scan impedances of a subsection of dipoles at the center of the array is introduced. A hybrid method of moments/Green´s function technique is used to analyze the finite arrays of printed dipoles. Several numerical results are presented to demonstrate the accuracy of the new method in terms of predicting the blindness angle.
