8:30-9.15, IEEE APS-DL, Prof. Christophe Caloz, Real-Time Analog Signal Processing for Tomorrow’s Radio

École Polytechnique de Montréal, Canada



Today's exploding demand for faster, more reliable and ubiquitous wireless connectivity poses unprecedented challenges in radio technology. To date, the predominant approach has been to put increasing emphasis on digital signal processing (DSP). However, while offering device compactness and processing flexibility, DSP suffers of fundamental limitations, such as poor performance above the K band, high-cost A/D conversion, low processing speed and high power consumption.


Recently, Radio Analog Signal Processing (R-ASP) has emerged as a novel paradigm to potentially overcome these issues, and hence address the aforementioned challenges. R-ASP processes radio signals in their pristine analog form and in real time, using “phasers”. A phaser is a temporally – and sometimes also spatially – dispersive electromagnetic structure whose group delay is designed so as to exhibit the required (quasi-arbitrary) frequency function to perform a desired operation, such as for instance real-time Fourier transformation. Phasers can be implemented in Bragg-grating, chirped-waveguide, magnetostatic-wave and acoustic-wave technologies. However, much more efficient phasers, based on 2D/3D metamaterial structures and cross-coupled resonator chains, were recently introduced, along with powerful synthesis techniques. These phasers can manipulate the group delay of electromagnetic waves with unprecedented flexibility and precision, and thereby enable a myriad of applications in communication, radar, instrumentation and imaging, with superior performance or/and functionality. This talk presents an overview of R-ASP technology, including dispersion-based processing principles, historical milestones, phasing fundamentals, phaser synthesis, and many applications.


15:30-16:15, IEEE APS-DL, Prof. Karl F. Warnick, “Ultra-high Efficiency Phased Arrays for Astronomy, Remote Sensing, and Satellite Communications”, Brigham Young University, USA



Aperture phased arrays and phased array feeds (PAFs) are a promising technology for sensing and communications applications requiring electronic beam steering and large signal collecting area, but current technologies are too costly and inefficient for widespread use in satellite communications. To meet strict efficiency and sensitivity requirements, existing satellite communications terminals typically use reflector antennas with horn feeds. Because the microwave sky is quite cool, small improvements in antenna efficiency lead to large gains in the key figure of merit for a satellite receiver, signal to noise ratio. Horn antennas inherently have a high radiation efficiency, and off-the-shelf low noise block downcoverter feeds (LNBFs) cost only a few dollars to manufacture, yet have been so carefully optimized that further improving signal quality would require cryogenic cooling. These considerations have motivated significant recent interest in research aimed at achieving low cost, high efficiency phased array feed receiver systems. To meet this combination of high performance requirements and low cost, we have used computational design optimization to develop efficient, low noise planar array feed antennas that can be fabricated using standard microwave PCB techniques. This presentation gives an overview of work on passive, fixed beam array feeds with linear and circular polarization, including the first demonstration of planar phased arrays with performance comparable to traditional horn antennas, and active beam steering feeds that adaptively track a signal source as the antenna moves. This research opens up new possibilities for phased arrays in terms of low cost, high efficiency, and performance for satellite communications applications.
