Phase Agile Bst-Loaded Dual Resonance Reflectarray Design At KA-Band

Abstract

In this paper, a Ka-band tunable dual resonance reflectarray element, its design methodology, limitations, and design tradeoffs are presented. Tunability is achieved by loading the antenna element with Barium Strontium Titanate (BST) thin film. The effects of limited frequency tuning, coupling conditions, and inherent loss is investigated using full-wave simulations. A unit cell design demonstrating an overall phase range of 360° and an average loss of 8.25 dB at 30.97 GHz is realized.
