Abstract:
1. A system comprising: an amplifier; a dipole antenna; and a micro-electromechanical system (“MEMS”) switch coupled in series with the amplifier and the antenna, the MEMs switch including: an actuation electrode disposed on a substrate; a suspended electrode suspended proximate to the actuation electrode, the suspended electrode including at least three support members and a plate member, each of the at least three support members are clamped at both ends to the substrate via anchors, the plate member supported by the at least three support members; a first signal line coupled to the suspended electrode; and a second signal line positioned proximate to the suspended electrode to form a closed circuit with the suspended electrode and the first signal line when an actuation voltage is applied between the actuation electrode and the suspended electrode that causes the suspended electrode to electrostatically pull towards the actuation electrode.
