Aperture stacked microstrip equal/unequal power divider

An aperture stacked in-phase power divider is designed, where unequal 7:1 power division can be achieved without any difficulty in microstrip realization. The simulated and experimental results of equal and unequal power split are presented to demonstrate low insertion loss, high isolation between the output ports and large impedance bandwidth. © 2012 Wiley Periodicals, Inc.
