OTTAWA, CANADA: C-COM Satellite Systems Inc. has developed a patent pending technology to be used with its next generation in-motion phased array antennae.
This technology has been developed in partnership with the University of Waterloo as part of an engineering graduate research project under the guidance of Dr. Safieddin (Ali) Safavi-Naeini, director of the Centre for Intelligent Antenna and Radio Systems. The low cost phase shifter is fully compatible with commercial planar technologies currently under consideration for low-profile two-way phased-array systems for land-mobile satellite communication.
"The phased-array under development uses a unique phase shifter technology based on an electrically controlled material that changes the propagation characteristics and phase in a fast and smooth manner," said Dr. Safieddin Safavi-Naeini, a professor at the Department of Electrical and Computer Engineering at the University of Waterloo.
"No appreciable loss is observable in a very small foot print over the entire Ka-band range. The new concept is fully compatible with low-cost integrated passive technologies for large arrays. Another unique characteristic of this technology is its almost phase-shift independent insertion loss, which will pave the way for a fully passive phased-array technology - the Holy Grail of the intelligent antenna community."
