Реферат: front page image
(EN) The invention relates to an ultra-wideband high-gain omnidirectional antenna. Two same radiating units are in serial connection to an insulating support tube at equal interval, and a power distributor is arranged on an installation base and respectively in electric connection with the two radiating units through two feeder cables in the insulating support tube. Each radiating unit comprises an upper metal cone cage barrel and a lower metal cone cage barrel, wherein the upper metal cone cage barrel is the same as the lower metal cone cage barrel, the upper metal cone cage barrel and the lower metal cone cage barrel are oppositely arranged, an opening of the upper metal cone cage barrel is arranged upwards, vibrators at the opening position of the upper metal cone cage barrel are bent inwards the upper metal cone cage barrel to form a coaxial small cone cage, all vibrators at the convergence opening position of the small cone cage respectively, vertically and downwards extend to form a small cylinder cage, vibrators at the opening positions of the metal cone cage barrels of the radiating units are bent inwards to form small cone cages, and vibrators at the convergence opening position of the cone cage respectively and vertically extend downwards to form a small cylinder cage. Double barrels and double cones are arranged in the same direction, vertical polarization is achieved, the size of the omnidirectional radiating antenna is reduced to one fourth of the wavelength of a low frequency band, the bandwidth is increased, and the gain is improved.
(ZH) 本发明涉及一种超宽带高增益全向天线,两个相同的辐射单元等距串接于绝缘支撑管,功率分配器设置于安装底座上并经绝缘支撑管内的两路馈电电缆与两个辐射单元分别电连接,辐射单元包括相对设置的上下两个相同的金属圆锥笼筒,上金属圆锥笼筒开口朝上,上金属圆筒的开口处振子弯折到圆筒内部形成一个同轴的小圆锥笼,小圆锥笼收口处各振子分别向下竖直延长形成小的圆筒笼,金属圆锥笼筒辐射单元圆锥笼筒的开口处的振子弯折到内部形成一个小圆锥笼,且圆锥笼收口处的各振子分别垂直向下延长,又形成一个小的圆筒笼,形成双筒双锥同向,垂直极化,全方位辐射天线的尺寸缩短至低频段的四分之一波长,增加了带宽,提高了增益。
