This paper presents for the first time an X-band antenna array with integrated silicon germanium low noise amplifiers (LNA) and 3-bit phase shifters (PS). LNAs and PSs were successfully integrated onto an 8 × 2 lightweight antenna utilizing a multilayer liquid crystal polymer (LCP) feed substrate laminated with a duroid antenna layer. A baseline passive 8×2 antenna is measured along with a SiGe integrated...
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.
