Application of RF MEMS Switch for Reconfiguring Micromachined Antennas

Abstract:

For mobile and wireless applications where the size of the system has to be minimized, antenna and RF components are to be integrated on to the same substrate. The contradicting requirements of the substrate with respect to the antenna and the RF circuit can be resolved by using micromachined antennas. If the principle of reconfigurability is applied to the micromachined antenna, it increases the versatality of the system. This paper proposes reconfigurability of micromachined antennas using RF MEMS switches. In the case of micromachined antennas, which involve low voltage signals, RF MEMS switches with low actuation voltage are required for achieving reconfigurability. In this paper an RF MEMS capacitive switch operating at a low actuation voltage of 1 Volt is presented
