  • Abstract
    This article presents the design and performance of tunable components and circuits for mobile device antennas based on Agile´s barium strontium titanate (BST) thin film technology. A novel capacitor array has been designed utilizing a nonlinear BST capacitance model and a capacitor array “stacking” technique. Measurements on mobile devices demonstrate extended bandwidth coverage for LTE, cellular, and PCS bands while maintaining TRP and TIS, and in some cases improvement over fixed solutions.
