命名为4581XH新系列的毫米波抛物面圆盘天线可用于八种不同的波导段,频率范围为26.5-170GHz,并有六种不同的尺寸。最小的一种,圆盘直径为4英寸,与一个初级焦点馈电器混成一体。其它还有10,12,18,24,36英寸的,采用卡塞格伦馈电器。据说,上述这些圆
The new series of 4581XH millimeter-wave parabolic dish antennas are available in eight different waveguide sections in the frequency range of 26.5-170 GHz in six different sizes. The smallest, four-inch disk diameter, is integrated with a primary focus feed. There are other 10,12,18,24,36-inch, with Cassegrain feed. It is said that these circles
