Pneumatically-Actuated Liquid Metal-Based Frequency Reconfigurable Antenna.

ABSTRACT: Software-defined radios and cognitive radios can switch their operating frequency across a wide range. Although analog and digital circuits enable cross-frequency operation of much of the RF frontend, there is a lack of practical antennas that are frequency-reconfigurable over such a wide range. Prior rigid antennas are either narrow-band with high radiation efficiency, or wide-band with low radiation efficiency. This study presents a soft, stretchable, compact, omnidirectional liquid metal composite antenna system to enable high radiation efficiency when reconfiguring to different frequencies across a wide band. On the hardware front, an extendable multi-branch stretchable liquid metal based antenna geometry is optimized that preserves high efficiency when switching across a wide range of
