    • A dipole having radiating elements (9, 14) which taper from the proximal end (1) of the radiating element to the distal end (2) of the radiating element. Electrical coupling is provided between adjacent lateral edges of the radiating elements by means of spaced apart tabs (10, 11, 12, 13). Cut-away portions (5, 5a) are provided between the proximal end (1) and the tabs (3, 4). By adjusting the distance between and the extent to which the tabs (10, 11, 12, 13) overlap the real part of the impedance of the dipole may be adjusted. The dipole may thus be configured to be directly driven from a feed-line without requiring matching components. This results in reduced complexity and losses. The dipole also exhibits reduced impedance variation, increasing the bandwidth of the dipole.
    • 具有从辐射元件的近端(1)到辐射元件的远端(2)渐缩的辐射元件(9,14)的偶极子。 通过间隔开的突片(10,11,12,13)在辐射元件的相邻侧边缘之间提供电耦合。 切口部分(5,5a)设置在近端(1)和突片(3,4)之间。 通过调整突片(10,11,12,13)之间的距离和其间的重叠程度,可以调节偶极子的阻抗的实部。 因此偶极子可被配置为直接从馈电线驱动而不需要匹配的部件。 这导致复杂性和损失的降低。 偶极子还表现出减小的阻抗变化,增加偶极子的带宽。

    • A variable differential phase shifter is provided. The device provides a continuous variation in phase between two outputs derived from a single input. The device is suitable for application at signal frequencies around 900 MHz, and is constructed in the form of an inner (38) and outer (37) sleeve capacitively coupled to an inner conductive rod (24) and outer conductive tube (26) respectively, wherein the inner (38), and outer (37) sleeves are connected to an input and can be moved in fixed relative relation thereby varying the phase relationship between the two outputs which are connected to the inner rod (24) and outer tube (26). A dielectric layer (25 and 27) may be provided around the inner rod (24) and outer tube (26). An unequal power division version of the device is provided for by the inclusion of a dielectric tube surrounding a portion of the inner rod.
