Abstract

A pattern and polarization reconfigurable helix antenna with mechanically actuated liquid metal in a helical channel is presented for L1 frequency band (1.575 GHz). The antenna is composed of a flexible polymer tube shaped into a helix which is filled in and out with a peristaltic micropump. The mic...
