【摘要】：天線是無線通信系統(tǒng)極其關(guān)鍵的部件之一，無線通信技術(shù)的發(fā)展對天線的電性能也提出了新的要求，小型化、多頻帶/寬頻帶技術(shù)成為天線的熱點(diǎn)技術(shù)。圓極化天線由于其廣泛的實(shí)用價(jià)值也頗受天線工程師青睞。本文結(jié)合實(shí)際需求，設(shè)計(jì)了一款新型小型化雙頻雙圓極化微帶天線，其特點(diǎn)為天線尺寸小，雙頻比小。 第一部分介紹了小雙頻比雙圓極化微帶天線的研究背景，分類總結(jié)了近年來雙頻雙圓極化微帶天線的常見形式，，結(jié)合國內(nèi)外研究現(xiàn)狀，分析了該課題的技術(shù)難點(diǎn)。 第二部分介紹了微帶天線的基本理論與技術(shù)。微帶天線的基本理論包括微帶天線的分類、優(yōu)缺點(diǎn)及分析方法，微帶天線的基本技術(shù)包括圓極化技術(shù)、小型化技術(shù)和雙頻技術(shù)。為解決本課題的技術(shù)難點(diǎn)提供理論與技術(shù)支持。 第三部分介紹了三種較為新型的單頻小型化圓極化微帶天線，分析了天線參數(shù)對性能影響。為雙頻雙圓極化微帶天線的設(shè)計(jì)做技術(shù)準(zhǔn)備。 第四部分首先介紹了雙頻雙圓極化天線的設(shè)計(jì)指標(biāo)，分析天線的設(shè)計(jì)難點(diǎn)，經(jīng)過反復(fù)嘗試，最終確定了雙頻雙圓極化微帶天線設(shè)計(jì)方案：通過層疊結(jié)構(gòu)實(shí)現(xiàn)雙頻；通過不同的曲流技術(shù)實(shí)現(xiàn)各自的小型化。通過HFSS仿真分析該天線的工作原理以及優(yōu)缺點(diǎn)，與實(shí)測結(jié)果進(jìn)行對比，結(jié)果吻合良好。
[Abstract]:Antenna is one of the most important components of wireless communication system. The development of wireless communication technology has put forward new requirements for antenna electrical performance and miniaturization. Multi-band / wide-band technology has become a hot technology of antenna. Circular polarization antenna is also favored by antenna engineers because of its extensive practical value. A new miniaturized dual-frequency dual-circularly polarized microstrip antenna is designed, which is characterized by a small size and a small dual-frequency ratio. The first part introduces the research background of dual-circular polarization microstrip antenna with small dual-frequency ratio, classifies and summarizes the common forms of dual-frequency dual-circularly polarized microstrip antenna in recent years, combined with the current research situation at home and abroad. The technical difficulties of this subject are analyzed. The second part introduces the basic theory and technology of microstrip antenna. The basic theory of microstrip antenna includes the classification, advantages and disadvantages of microstrip antenna, and the basic technology of microstrip antenna including circular polarization technology. Miniaturization technology and dual-frequency technology. Provide theoretical and technical support for solving the technical difficulties of this subject. In the third part, three new microstrip microstrip antennas with single frequency miniaturization are introduced, and the effects of antenna parameters on the performance are analyzed. The technical preparation for the design of dual-frequency circularly polarized microstrip antennas is made. In the 4th part, the design index of dual-frequency and double-circular polarization antenna is introduced, and the design difficulty of the antenna is analyzed, which has been tried again and again. Finally, the design scheme of dual-frequency dual-circularly polarized microstrip antenna is determined: the dual-frequency antenna is realized by cascading structure; The miniaturization of the antenna is realized by different curved flow techniques. The working principle, advantages and disadvantages of the antenna are analyzed by HFSS simulation, and the results are in good agreement with the measured results.
