Flexible active antenna arrays

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