Abstract
A switch includes at least two distributed constant lines (21a, 21b) disposed close to each other, a movable element (11) arranged above the distributed constant lines so as to oppose these distributed constant lines and connecting the distributed constant lines to each other in a high-frequency manner upon contacting the distributed constant lines, and a driving means (4) for displacing the movable element by an electrostatic force to bring the movable element into contact with the distributed constant lines. The movable element has at least two projection (32a-32d) formed by notching an overlap portion of the movable element which is located on at least one distributed constant line. The projections oppose a corresponding distributed constant line.
Claims23
A micromachine switch characterized by comprising:
- at least two distributed constant lines disposed close to each other;
- a movable element arranged above said distributed constant lines such that distal end portions of said movable element oppose said distributed constant lines, respectively, and connect said distributed constant lines to each other in a high-frequency manner upon contacting said distributed constant lines;
- and
- driving means for displacing said movable element by an electrostatic force to bring said movable element into contact with said distributed constant lines,
- wherein said movable element has at least two projections formed by notching an overlap portion of said movable element which is located on at least one distributed constant line side, and
- the projections oppose a corresponding distributed constant line.
A micromachine switch characterized by comprising:
- at least two distributed constant lines disposed close to each other;
- a movable element arranged above said distributed constant lines such that distal end portions of said movable element oppose said distributed constant lines, respectively, and include a conductor;
- and
- driving means for displacing said movable element by an electrostatic force to bring said movable element into contact with said distributed constant lines,
- wherein at least one of said distributed constant lines has at least two projections formed by notching an overlap portion of said at least one of said distributed constant lines, and
- the projections oppose said movable element.
A micromachine switch characterized by comprising:
- at least two distributed constant lines disposed close to each other;
- a movable element arranged above said distributed constant lines such that distal end portions of said movable clement oppose said distributed constant lines, respectively, and connect said distributed constant lines to each other in a high-frequency manner upon contacting said distributed constant lines;
- and
- driving means for displacing said movable element by an electrostatic force to bring said movable element into contact with said distributed constant lines,
- wherein at least one of said distributed constant lines has at least two first projections formed by notching an overlap portion of said at least one of said distributed constant lines, and
- said movable element has at least two second projections so formed as to oppose the first projections of said at least one of said distributed constant lines by notching an overlap portion of said movable element.
