    • An ultra wideband antenna comprises a substrate (21). A metal layer deposited on the substrate comprises first and second non-metallic regions (22a, 22b) defined therein. The first and second non-metallic regions (22a, 22b) are arranged on either side of a longitudinal axis (X0), the longitudinal axis (X0) corresponding to a feed axis of the antenna. The first and second non-metallic regions taper towards the first longitudinal (X0) to form a bowtie pattern. Each of the first and second non-metallic regions (22a, 22b) comprises at least one tuning slot (31, 33), the at least one tuning slot (31, 33) being arranged about a respective first axis (X1, X2), the first axis (X1, X2) being parallel to the longitudinal axis (X0), and wherein the at least one tuning slot extends along its respective axis (X1, X2) to form a non-metallic area outside the non-metallic area defined by the respective first and second non-metallic region (22a, 22b). The tapering of the first and second non-metallic regions (22a, 22b) in combination with the at least one pair of tuning slots (31, 33) enables the antenna to be reduced in size, while being capable of operating over at least the UWB frequency range.
    • 超宽带天线包括基板(21)。 沉积在基板上的金属层包括限定在其中的第一和第二非金属区域(22a,22b)。 第一和第二非金属区域(22a,22b)布置在纵向轴线(X0)的两侧,纵轴线(X0)对应于天线的进给轴线。 第一和第二非金属区域朝向第一纵向(X0)逐渐变细以形成弓形图案。 第一和第二非金属区域(22a,22b)中的每一个包括至少一个调谐槽(31,33),所述至少一个调音槽围绕相应的第一轴线(X1,X2)布置, 所述第一轴线(X1,X2)平行于所述纵向轴线(X0),并且其中所述至少一个调音槽沿其相应的轴线(X1,X2)延伸以在所述非金属区域外部形成非金属区域 由相应的第一和第二非金属区域(22a,22b)限定。 第一和第二非金属区域(22a,22b)与至少一对调谐槽(31,33)组合使得天线能够减小尺寸,同时能够至少操作天线 UWB频率范围。
