摘要： A micro-machine switch in accordance with the present invention includes a supporter having a predetermined height relative to a surface of a substrate, a flexible cantilever projecting from the supporter in parallel with a surface of the substrate, and having a distal end facing a gap formed between two signal lines, a contact electrode formed on the cantilever, facing the gap, a lower electrode formed on the substrate in facing relation with a part of the cantilever, and an intermediate electrode formed on the cantilever in facing relation with the lower electrode. The micro-machine switch can operate at a lower drive voltage than a voltage at which a conventional micro-machine switch operates, and can enhance a resistance of an insulating film against a voltage.

摘要： A relatively small phased array antenna is formed at a low cost even if the number of radiating elements increases in order to improve the gain. The phased array antenna has a multilayered structure in which a number of radiating elements (15), a phase shift unit (16) for changing the phase of an RF signal transmitted/received at each radiating element, and a distribution/synthesis unit (14) are formed on different layers. Signal lines (X1 - Xm) and scanning lines (Y1 - Yn) are wired on a phase control layer (35) to connect phase shift units to each other in a matrix. The signal lines and the scanning lines are matrix-driven by selection units (12X, 12Y) so that desired phase shift amounts are set to phase shift units located at the intersections of the signal and scanning lines. In addition, switches (17S) of a phase shifter (17) are formed at once on the phase control layer.

摘要： A micromachine switch for use in a millimeter wave circuit and a microwave circuit is simpler in structure than conventional micromachine switches. The micromachine switch has first and second high-frequency signal lines (1b, la), cantilever (11) fixed to an end of the first high-frequency signal line (1b) and extending to a position above second high-frequency signal line (1a), first insulating means (15) disposed on second high-frequency signal line (1a), second insulating means (14) disposed in an area where cantilever (11) and second high-frequency signal line (1a) confront each other, and first control signal line (2) connected between an end of second high-frequency signal line (1a) and first insulating means (15), for applying a control signal. When the control signal is applied to second high-frequency signal line (1a), cantilever (11) is attracted to second high-frequency signal line (1a), and connected to second high-frequency signal line (1a) via second insulating means (14) in a high-frequency fashion.
