摘 要：Complex and dynamic control of radiated fields are advantageous for flexible radio systems,which naturally move,roll,bend,twist,deform,and *** challenges hinder the proliferation of these antenna *** work shows how using radiofrequency microchips reduces system component count,decreases mass to~0.1 g cm−2,and increases functionality and mechanical *** develop a general platform for large scale flexible arrays and demonstrate two different 256-elements,30×30 cm2 flexible *** varying supply distribution methods and radiators we show how performance can be optimized for maximum power delivery or physical *** demonstrated systems conform to curved surfaces with radii of curvatures as low as 23 cm and wirelessly deliver~80 mW of DC power to a 6.7 cm×11 cm-receiver over one meter *** paves the way towards the integration of smart arrays in flexible wearables and deployable lightweight airborne systems.
