Abstract :
A liquid-metal reconfigurable log-periodic balun is presented. The design consists of three sections that can be independently actuated with pressure-driven liquid metal, resulting in a planar balun that is capable of switching between three continuous bands from 1.89 to 8.45 GHz. The two output ports have a magnitude balance within 1 dB and a phase difference within 10° of 180°.
