【摘要】：基站天線是移動(dòng)通信重要組成部分之一。近年來移動(dòng)通信發(fā)展速度越來越快,第四代通信技術(shù)已經(jīng)逐漸成熟。為了節(jié)省基站的站址安裝資源,減少網(wǎng)絡(luò)建設(shè)成本,對(duì)寬頻基站天線的研究顯得至關(guān)重要。多陣列寬頻雙極化天線覆蓋多個(gè)頻段,性能優(yōu)越,能夠滿足通信技術(shù)的需求。本論文主要研究了輻射單元、多陣列天線、內(nèi)置合路器天線以及饋電網(wǎng)絡(luò)。論文主要研究內(nèi)容可概括為一下幾個(gè)部分。天線輻射單元是天線的基礎(chǔ)。本文設(shè)計(jì)了一種雙極化低駐波高隔離度的寬頻基站天線輻射單元。輻射單元基于互補(bǔ)性天線源原理進(jìn)行設(shè)計(jì),主要由正交放置的兩對(duì)方形偶極子天線、圓形支撐座、雙倒L型饋電線、反射板組成。既滿足了方向圖指標(biāo)要求,也保證了電路參數(shù)駐波比和隔離度。使用HFSS電磁仿真軟件對(duì)多陣列天線以及內(nèi)置合路器天線進(jìn)行了仿真設(shè)計(jì),研究不同參數(shù)對(duì)其水平波寬、前后比以及交叉極化比的影響。使用AWR軟件對(duì)天線指標(biāo)進(jìn)行優(yōu)化,使實(shí)際天線指標(biāo)達(dá)到穩(wěn)定。饋電網(wǎng)絡(luò)是天線重要的一部分,能與輻射單元共同保證天線性能。最后一章從理論分析了相控陣天線的原理,分別對(duì)功率分配器、移相器進(jìn)行了簡單的研究。再利用功分器、移相器設(shè)計(jì)一種新型饋電網(wǎng)絡(luò),完成波束賦形,使天線增益、旁瓣抑制等指標(biāo)滿足移動(dòng)通信的要求。
[Abstract]:Base station antenna is one of the important components of mobile communication. In recent years, mobile communication is developing more and more quickly, 4th generation communication technology has been gradually mature. In order to save the base station site installation resources. Reducing the cost of network construction is very important to the research of broadband base station antenna. The multi-array broadband dual-polarization antenna covers multiple frequency bands and the performance is superior. Can meet the needs of communication technology. This paper mainly studies the radiation unit, multi-array antenna. Built-in combiner antenna and feed network. The main research contents of this paper can be summarized as follows. Antenna radiation unit is the basis of antenna. In this paper, a broadband base station antenna with dual polarization and low standing wave isolation is designed. Radiation units. The radiation units are designed based on the principle of complementary antenna sources. It is mainly composed of two pairs of square dipole antenna, circular support seat, double inverted L-type feed line and reflector, which meet the requirements of the pattern. The HFSS electromagnetic simulation software is used to simulate and design the multi-array antenna and the built-in combiner antenna, and the horizontal wave width of different parameters is studied. The AWR software is used to optimize the antenna index to make the antenna index stable. The feed network is an important part of the antenna. In the last chapter, the principle of phased array antenna is analyzed theoretically, and the power divider and phase shifter are studied simply. The phase shifter designs a new type of feed network, which completes the beamforming and makes the antenna gain and sidelobe suppression meet the requirements of mobile communication.
