【摘要】：相控陣天線在軍事領(lǐng)域、天文學(xué)領(lǐng)域和現(xiàn)代通信系統(tǒng)中均有廣泛應(yīng)用,這些系統(tǒng)均重點(diǎn)考察相控陣天線的遠(yuǎn)場特性。近期,相控陣天線在近場輻射的應(yīng)用也逐漸受到了重視。而近場聚焦天線可以把電磁能量像透鏡一樣聚焦到近場的任意一點(diǎn),減少能量在空間中的浪費(fèi)。隨著工業(yè)通信的發(fā)展及人們對電磁污染越來越重視,近場聚焦天線越來越重要。本論文開展了相控陣天線在近場聚焦中的研究與應(yīng)用這一課題。論文主要內(nèi)容如下:首先,本文簡明扼要地介紹了有關(guān)聚焦陣天線的研究背景、意義及本課題在國內(nèi)外的研究發(fā)展概況。同時(shí),詳細(xì)闡述了相控陣的基本原理以及傳統(tǒng)近場聚焦陣天線的實(shí)現(xiàn)方法,并引出了基于可重構(gòu)天線單元的新型近場聚焦陣天線,介紹了該種思想的優(yōu)勢。其次,設(shè)計(jì)了4×4、6×6及8×8的聚焦陣天線,詳細(xì)給出了新型近場聚焦陣天線仿真模型的設(shè)計(jì)過程。這些模型均采用了方向圖可重構(gòu)天線單元,并與傳統(tǒng)聚焦陣天線的聚焦性能作對比,結(jié)果表明聚焦陣天線規(guī)模越大,新型聚焦陣的聚焦增益比傳統(tǒng)聚焦陣的聚焦增益越大,充分證明了新型聚焦陣天線的優(yōu)勢。第三,本文選取6×6新型近場聚焦陣天線進(jìn)行加工測試,測試結(jié)果與仿真結(jié)果相吻合,證明了將可重構(gòu)天線單元與傳統(tǒng)近場聚焦陣天線相結(jié)合的可行性。
[Abstract]:Phased array antennas are widely used in the field of military, astronomy and modern communication systems. These systems all focus on the far field characteristics of phased array antennas. In the near future, the application of phased array antennas in near field radiation has also been paid more attention. One point is to reduce the waste of energy in space. With the development of industrial communication and more and more attention to electromagnetic pollution, the near-field focusing antenna is becoming more and more important. This paper has carried out the research and application of phased array antenna in the near field focusing. The main contents of this paper are as follows: first, this paper briefly introduces the focus on focus. At the same time, the basic principle of the phased array and the implementation of the traditional near field focused array antenna are described in detail, and a new near field focused array antenna based on reconfigurable antenna element is introduced, and the advantages of this idea are introduced. Secondly, 4 x 4,6 x 6 is designed. And 8 x 8 focusing array antenna, the design process of the new near field focused array antenna simulation model is given in detail. These models all use the directional image reconfigurable antenna element, and compare with the focusing performance of the traditional focusing array antenna. The results show that the larger the size of the focusing array antenna, the focusing gain of the new focusing array is more than the traditional focusing array. The bigger Jiao Zengyi is, it fully proves the advantages of the new focusing array antenna. Third, this paper selects 6 * 6 new near field focused array antennas for processing and testing. The test results coincide with the simulation results, which proves the feasibility of combining the reconfigurable antenna element with the traditional near field focusing array antenna.
