PACMAN’s goal was to research and develop integrated technology for the design and manufacturing of mass-market, low cost phased array antennae that can be applied in various domains, such as telecom, wireless internet, satellite communication, radars, large area astronomic antennae, automotive and security. The targeted cost price reduction is, depending on the application area, at least a factor of 10. If successful, mass-markets with high volumes and relatively high added value can then be developed, based on these new technologies.
A phased array is a group of transducers that operate together with relative time, or phase shifts between the elements. The combined elements act as a single instrument that can be steered to distinct points in space. Arrays can be designed for transmitting and receiving electromagnetic and acoustic waves. Phased array systems are often referred to as Electronically Steered Array (ESA) systems. In general, one can say that the enormous flexibility of phased array antennas, caused by the fact that one can electronically direct its beam(s) and so get time/energy efficiency, is an essential element in enabling the enormous increase we see in wireless communication.
