Coupled-Oscillator Based Active-Array Antennas

Preface

This book is a compilation of research results obtained primarily over the past two decades in the application of groups of oscillators coupled in various configurations to the excitation of phased-array antennas. Much of the work was carried out at the Jet Propulsion Laboratory of the California Institute of Technology under contract with the National Aeronautics and Space Administration (NASA) building on the early work at the University of Massachusetts, Cornell University, and the University of California, Santa Barbara. More recent work at several institutions in Spain and especially at the Centre Tecnologic de Telecomunicacions de Catalunya (CTTC), as well as at a variety of institutions across Europe and Asia, is also described. A motivation for much of this work was the promise of a method of providing beam agility at electronic speed that is simpler than the conventional method of using a phase shifter at each element or module and controlling these phase shifters in a coordinated manner. More generally, however, the effort has focused on the integration of transmitter, receiver, and antenna including the beam-steering function in a single planar package.

The intended audience for the book comprises primarily designers of phased-array antennas and the associated electronics, but the book may also be of interest to those who may, through understanding the principles presented, envision other innovative applications of oscillator arrays such as distribution of ...
