    • An antenna system is described including a reflector antenna, responsive to radio frequency signals at a first frequency, having a first reflector surface, a second reflector surface and a Cassegrain feed. The antenna system further includes an array antenna having a plurality of antenna elements responsive to radio frequency signals having a second different frequency, wherein a center element is in a common location with the feed of the reflector antenna. With such an arrangement, an improved dual band antenna system is provided. By providing the center element of the array antenna in a common location with the feed of the reflector antenna, a dual band radio frequency antenna system is provided which is more compact with improved radiation characteristics than known similar configured antennas.
    • 描述了一种天线系统,其包括响应于第一频率的射频信号的反射器天线,具有第一反射器表面,第二反射器表面和卡塞格莱恩馈电。 天线系统还包括阵列天线,其具有响应于具有第二不同频率的射频信号的多个天线元件,其中中心元件与反射器天线的馈送处于公共位置。 通过这样的布置,提供了改进的双频带天线系统。 通过将阵列天线的中心元件设置在与反射器天线的馈送的公共位置中,提供了双频带射频天线系统,其比已知的类似配置的天线更加紧凑,具有改进的辐射特性。
