    • 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.
    • 即使辐射元件的数量增加以增加增益,也以低成本形成相对小的相控阵天线。 相控阵天线具有多层结构,其中多个辐射元件(15),用于改变在每个辐射元件处发射/接收的RF信号的相位的相移单元(16)和分布/合成单元(14) )形成在不同的层上。 信号线(X1-Xm)和扫描线(Y1-Yn)被布线在相位控制层(35)上,以将矩阵中的相移单元相互连接。 信号线和扫描线由选择单元(12X,12Y)进行矩阵驱动,使得期望的相移量被设置为位于信号和扫描线的交点处的相移单元。 此外,移相器(17)的开关(17S)一次形成在相位控制层上。

    • A micromachine switch includes a driving part (12) for displacing a contact (11) on the basis of a control signal, a first control signal line (4) for applying the control signal to the driving part, and a first RF signal inhibiting part (3) connected to the first control signal line to inhibit, from passing therethrough, an RF signal flowing RF signal lines (1a, 1b). With this arrangement, an insertion loss of the micromachine switch can be reduced, and the RF characteristic of a circuit using the micromachine switch can be improved.
    • 微机械开关包括用于基于控制信号移动触点(11)的驱动部分(12),用于将控制信号施加到驱动部分的第一控制信号线(4)和第一RF信号抑制部分 (3),连接到第一控制信号线,以阻止流过RF信号线(1a,1b)的RF信号。 通过这种布置,可以减小微机械开关的插入损耗,并且可以提高使用微机械开关的电路的RF特性。
