Abstract
In this work, ohmic contact series cantilever RF MEMS switches are used to reconfigure a planar dipole antenna in order to exhibit the same radiation pattern and good impedance matching at any frequency in the X-band range. The antenna is fabricated on a silicon substrate and the desired reconfigurability is achieved with four switches, each one shifting the resonant frequency by 900 MHz approximately. For the successful integration of the system, the antenna and the switches are fabricated from the same materials. Issues regarding the biasing of the switches and the antenna feed are resolved herein.
