    • A phased array antenna system includes a first radiation element that is made of a material and has a length selected to resonate at a desired frequency. A phase-shift element is coupled to one end of the first radiation element. A second radiation element is coupled to the end of the phase-shift element opposite the first radiation element, so that a radio signal passes through the first radiation element through the phase-shift element and through the second radiation element, the second radiation element is made of a material and has a length selected to resonate such that the first and second radiation elements cooperate to form a desired beam pattern from the antenna system.
    • 相控阵天线系统包括第一辐射元件,该第一辐射元件由材料制成并且具有被选择以期望频率谐振的长度。 相移元件耦合到第一辐射元件的一端。 第二辐射元件耦合到与第一辐射元件相对的相移元件的端部,使得无线电信号通过相移元件并通过第二辐射元件穿过第一辐射元件,第二辐射元件是 由材料制成并且具有被选择为谐振的长度,使得第一和第二辐射元件协作以从天线系统形成期望的波束图案。
