【摘要】：該文設(shè)計(jì)并制作了一種基于超材料的高增益寬帶雙極化天線,該天線由兩個(gè)正交放置的印刷振子單元、饋電巴倫及金屬接地板構(gòu)成。為了進(jìn)一步展寬帶寬、提高增益,在天線上了加載開口諧振環(huán)、互補(bǔ)開口諧振環(huán)等超材料結(jié)構(gòu)。測試結(jié)果表明,該天線回波損耗小于-10 d B的帶寬約為69%(0.98~2.01 GHz),在相同的頻帶內(nèi)隔離度大于20 d B。由于開口諧振環(huán)的引向作用,天線的輻射特性得到改善,增益最大提高了4.1 d B左右。和已有設(shè)計(jì)相比,該天線的總體高度減小了約12%。其可以當(dāng)作獨(dú)立天線使用,也可用作反射面天線的雙極化饋源。
[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.
