Abstract :
A new class of reconfigurable antenna based on monopole structures containing liquid dielectrics is presented. It was determined that the operating principle of this class of antenna is essentially that of a dielectric resonator, where salt (in solution) modifies the dielectric properties. The resonator column height determined the operating frequency, allowing match and frequency of operation to be fully tunable over 1-2.5 GHz while salinity mainly influences the bandwidth.
