The current state of the reflector antenna art - entering the 1990's
Article Abstract:
An overview of the state of the art of reflector antenna theory is presented. Specific areas covered include shaped multiple reflectors, reflector surface metrology, and the outlook for future advances in reflector antenna technology. The laws of geometrical optics can be use to create shaped multiple reflector antennas with arbitrary aperture distributions. A very high aperture efficiency can be gained by combining a highly tapered feed, a properly shaped subreflector and a slightly distorted main reflector. Reflector surface metrology affects reflector antenna design because the manufacture of reflector panels is crucial to the performance of the antenna. Finally, the future of reflector antenna technology lies in using technology similar to that employed in large optical telescopes.

Antenna theory: a review
Article Abstract:
Antenna theory has progressed tremendously since Guglielmo Marconi first performed a transatlantic transmission in 1901. The history of antenna theory is reviewed and introductory material on the basics of antenna theory is presented. Included are reviews of Maxwell's equations, electromagnetic boundary conditions, equations of radiation, and principles of antenna radiation. Other subjects covered in this paper are arraying principles, advanced asymptotic techniques for antenna analysis and design, modelling of antenna source excitation and figures-of-merit. Also presented is a bibliography of books published in the field.

Antenna array architecture
Article Abstract:
An overview of the complex area of modern antenna array architecture is presented. Architecture refers to the method of building, or the structure of array antennas. The fundamental aspects of antenna design that must be considered when building an array system are stressed. They include electromagnetics, thermal properties and mechanical aspects. Also emphasized is the interaction between the design of an array aperture structure, corporate feeds, elements and devices. Finally, EHF monolithic array architecture is used as an example of a design problem.
