Multilayer organic X-band antenna arrays using Wilkinson power dividers with embedded thin film resistors

Wilkinson power dividers using embedded resistors were implemented in the feed networks of X-band microstrip antenna arrays of different sizes, and realized on a multilayer organic substrate. A thin film resistive foil is used to fabricate the resistors needed for the embedded Wilkinson dividers. Momentum simulation results show very good isolation between the output ports of the dividers.
