Study of EHF controlled-beam antennas for SATCOM : final report / J.L. Yen. : Co24-223/1-1982E-PDF

"A survey of three common classes of antennas namely, lens, reflector and microstrip array and a fourth, the less common reflector array for SATCOM at EHF is given. The optics and feeds for steerable multi-beam and phased-array antennas are discussed. A basic relation between antenna gain, size and scan angle or field of view is derived. Adaptive null steering for interference rejection is reviewed. The influence of antenna configuration on beam control performance is noted. An experimental study of an IF adaptive beam controller was undertaken. Advantages and disadvantages of IF analog implementation of beam control are discussed. Circuit components required for beam steering and control are also reviewed. The conceptual designs of a microstrip phased array for the ground segment and a controlled-beam reflector antenna system with hybrid steering are presented to illustrate the influence of the major issues. Finally, recommendations on promising technologies for further investigation and development are identified"--Summary, page 2.
