【摘要】：该文设计并制作了一种基于超材料的高增益宽带双极化天线,该天线由两个正交放置的印刷振子单元、馈电巴伦及金属接地板构成。为了进一步展宽带宽、提高增益,在天线上了加载开口谐振环、互补开口谐振环等超材料结构。测试结果表明,该天线回波损耗小于-10 d B的带宽约为69%(0.98~2.01 GHz),在相同的频带内隔离度大于20 d B。由于开口谐振环的引向作用,天线的辐射特性得到改善,增益最大提高了4.1 d B左右。和已有设计相比,该天线的总体高度减小了约12%。其可以当作独立天线使用,也可用作反射面天线的双极化馈源。
[Abstract]:In this paper, a high gain broadband dual-polarization antenna based on supermaterial is designed and fabricated. The antenna is composed of two orthogonal printed oscillator units, feed Barron and metal floor. In order to widen the bandwidth and increase the gain, the open resonant ring and complementary open resonant ring are loaded on the antenna. The test results show that the bandwidth of the antenna whose echo loss is less than -10 dB is about 69% (0.98 / 2.01 GHz),) and the isolation degree is greater than 20 dB in the same frequency band. The radiation characteristics of the antenna are improved due to the leading effect of the open resonant ring, and the maximum gain is increased about 4.1 dB. Compared with the existing design, the overall height of the antenna is reduced by about 12. It can be used as a separate antenna or as a dual polarization feed of a reflector antenna.
