Performance Analysis of a Three-Dimensional Microwave Lens in a Cylindrical Array Scanning Application.

Abstract

The calculated performance of a scanning cylindrical antenna array using a three dimensional lens system as the feed system is discussed. Nominal specifications of 4 deg beamwidth, 0.l deg pointing accuracy and 25 dB sidelobe level were established. The system was designed to scan through a full 360 deg of azimuth using associate phase shifters and sector switching matrix. It is shown that the evaluated lens system is unable to meet the sidelobe specification and suffers in this regard, and with regard to overall system loss, when compared to a more conventional matrix feed system.
