Mirror Antenna Dual-Band Lightweight Mirror Design

Abstract

The design of a dual-band half-wave-plate mirror for a two-axis beam scan mirror antenna is described. The solution for design parameters is given for perfect 90 polarization rotation at a given aspect angle for each of the two bands. The process for optimizing the design for the full desired range of aspect is described. Practical fabrication considerations are discussed along with inclusion of capacitive susceptance of a protective covering in the design theory. Calculated performance is compared with measurements of mirror samples.
