    • A phased antenna array (1) comprises a plurality of antennas (10) with a quarter wavelength transformer (12) and a phase delay element (14) inserted between adjacent antennas. Preferably, the antennas (10) are dipoles and have their lengths selected so that their input impedances become entirely real in the array environment. The quarter wavelength transformers (12) are connected to the input of the dipoles (10) and are designed to achieve a desired division of current among the antennas (10). The phase delay elements (14) introduce phase delays to steer the main beam of the antenna array (1) to a desired beam angle. The array may further comprise more than one column of antennas with the current distribution and the phasing between the columns being adjustable with a transformer. The array is formed on both sides of a flexible substrate and separated from a ground plane by a quarter wavelength.
    • 相控天线阵列(1)包括具有四分之一波长变换器(12)的多个天线(10)和相邻天线之间插入的相位延迟元件(14)。 优选地,天线(10)是偶极子并且选择它们的长度,使得它们的输入阻抗在阵列环境中变得完全是真实的。 四分之一波长变换器(12)连接到偶极子(10)的输入端,并被设计成在天线(10)之间实现期望的电流分配。 相位延迟元件(14)引入相位延迟以将天线阵列(1)的主波束转向期望的波束角。 阵列还可以包括具有电流分布的多于一列的天线,并且列之间的相位可以用变压器调节。 该阵列形成在柔性基板的两侧并与接地平面分开四分之一波长。
