Abstract :
A lumped element model of a popular commercial RF MEMS switch has been created that can be used for switches whose ground planes are floating. It enables more accurate simulation of reconfigurable antennas using these switches. Care must still be taken in designing a bias network for switches because DC bias lines that are not RF isolated can change the radiation characteristics in unpredictable ways.
