    • An antenna element (10) has two dielectric layers (12, 13), which separate three ground planes (17, 18, 21, 22, 23). The three ground planes have respective slots (26, 27, 28), which collectively define a slotline communicating at an inner end with a balun hole (57) that extends through all of the ground planes and dielectric layers. Two capacitive switches (121) are supported within the balun hole, and each have terminals respectively coupled to the same ground plane on opposite sides of the balun hole. The capacitive switches are independently and selectively operated to dynamically vary the impedance characteristic of the overall balun structure that includes the balun hole and two switch assemblies, and which gives the antenna element good electrical performance over a wide bandwidth. The antenna element includes a stripline (36), and a stripline to a slotline transition exists at the end of the slotline adjacent the balun hole.
    • 天线元件(10)具有分离三个接地平面(17,18,21,22,23)的两个电介质层(12,13)。 三个接地平面具有相应的槽(26,27,28),它们共同地限定了在内端连通的槽线,其中平衡 - 不平衡转换器(57)延伸穿过所有接地平面和电介质层。 两个电容式开关(121)支撑在平衡 - 不平衡转换器孔内,并且每个具有分别耦合到平衡 - 不平衡转换孔的相对侧上相同接地平面的端子。 电容式开关被独立地选择性地操作以动态地改变包括平衡 - 不平衡变压器孔和两个开关组件的整个平衡 - 不平衡变换器结构的阻抗特性,并且在宽带宽上给出天线元件良好的电性能。 天线元件包括带状线(36),并且在与平动不平衡变换器孔相邻的槽线的端部存在带状线到槽线转变。
