Abstract:
A miniature electromagnetic microwave switch for coplanar waveguide transmission lines comprising;(a) a first dielectric substrate having at least one input conducting electrode and at least one output conducting electrode deposited on front surface of said first dielectric substrate for propagation of microwave signals;(b) a cantilever with projection overlapping at least a part of said input conducting electrode and output conducting electrode;(c) a magnetic film deposited on a part of a front surface of said cantilever opposing said first dielectric substrate for actuating said cantilever and causing said microwave signals to propagate from said input conducting electrode to said output conducting electrode;(d) at least two conducting ground strips, one on each side of said input and output conducting electrodes to effect propagating of said microwave signals;(e) a first thin film electromagnetic coil on a back surface of said first dielectric substrate for actuating said cantilever, the center of said first thin film electromagnetic coil substantially coinciding with the center of said magnetic film.
