针对地面对长槽阵列天线阻抗带宽的影响问题,设计出一种在激励偶极子上实施加载的超宽带长槽天线,其阻抗匹配带宽显著增加,最终得到了超过3. 5:1 的阻抗匹配带宽;在扫描范围内具有稳定辐射特性。该天线具有超带宽、剖面低、易共形等特点,在超宽带小型化相控阵天线中有良好应用前景。

[Abstract]
For the impact of ground to long slot array impedance bandwidth, an ultra-wideband long slot antenna is designed to be loaded on the excitation dipole, and the impedance matching bandwidth increases significantly. Finally, a more than 3. 5:1 impedance matching bandwidth is obtained, and the radiation characteristic is stable in the scanning range. This long slot array has characteristic of broad bandwidth, low profile and easily conformal installation, which can be applied to small ultra-wideband phased antenna array system.
