MILLIMETER-WAVE ELECTRO-MECHANICAL STRIPLINE SWITCH

摘要

An electromechanical microswitch, comprising first and second electromagnets mounted in spaced-apart orientation to one another where each electromagnetic has a field center located a first distance above the mounting surface. A permanent magnet is positioned between the electromagnets and includes a magnetic field center that is higher above the mounting surface than that of the electromagnets so that the permanent magnet is magnetically biased toward the mounting surface. A stripline switch element is mountable between the permanent magnet and mounting surface, and biased against circuit structures on the mounting surface, whereby the stripline switch element moves between first and second activated positions under influence of the electromagnets.

1. An electromechanical microswitch, comprising:
first and second electromagnets mounted in spaced-apart orientation to one another on a mounting surface and defining a sliding volume between them, said first and second electromagnets each having an electromagnetic field center located a first distance above the mounting surface; a stripline switch element mountable to a surface substantially between the first and second electromagnets, said stripline switch including a fixed portion having an aperture defining a sliding boundary between the first and second electromagnets and a sliding portion received within the aperture for lineal movement between first and second activated positions, with said sliding portion including a facing portion directed toward the mounting surface and an opposing surface facing out of the aperture; and a permanent magnet coupled to the opposing surface of the sliding portion and mounted within the sliding volume between the first and second electromagnets, said permanent magnet having a magnetic field center located a second distance above the mounting surface, with the second distance being greater that the first distance so that the permanent magnet is biased toward the mounting surface.
