Abstract :
The design of a lightweight, low cost phased array antenna is presented. Multilayer printed wiring board (PWB) technology is utilized for RF and DC/logic manifold distribution. Transmit modules are soldered on one side and patch antenna elements are on the other, allowing the use of automated assembly processes. The 19 GHz antenna has two independently steerable beams, each capable of transferring data at 622 Mbit/s. A passive, self-contained phase change thermal management system is also presented
