Reconfigurable antennas provide a versatile solution to current demands in wireless communications, where multiple frequency bands are in use. Such antennas can change their properties, such as operational frequency, in response to a dynamic environment. This allows for cost-effective wireless communications systems which would otherwise require a dedicated antenna for every operational frequency band. This thesis presents a technique to realize a frequency-reconfigurable antenna using discrete amounts of electrically actuated liquid metal. The liquid metal functions as a pixel which, when made in an array, can create discrete conductive 2-D structures to use as an antenna.
