移動衛(wèi)星通信終端在海事、航空和陸地移動應用的商業(yè)市場中快速增長。近年來,隨著無線通信對小型天線需求的增加,引起了微波和射頻工程師對微帶貼片天線研究的廣泛發(fā)展,以改善增益、高數(shù)據(jù)速率通信,并補償某些陣元上的傳播損耗、旁瓣損耗、柵瓣和阻塞。因此,對能夠跟蹤衛(wèi)星并可應用于無線和雷達通信系統(tǒng)的輕質、低成本、易于制造、低剖面和可操縱的天線的需求顯著增加。由于在EM驅動的設計中所經(jīng)歷的挑戰(zhàn),已經(jīng)開發(fā)出了各種方法來減少在提高傳統(tǒng)的數(shù)值優(yōu)化技術的效率中的高成本,以使昂貴的計算模型得到更廉價和更快速的表示。此外,有源相控陣系統(tǒng)的校準受到溫度變化、移相器、陣列中的大量元素、互耦和功分器的影響。為了實現(xiàn)有源相控陣天線在某一特定方向上的高增益,在對沿波束方向的信號進行功率匯總測量時,精確控制每個陣元的相位、幅度和輻射方向圖是非常重要的。本文采用腔體模型作為粗模型,應用響應剩余空間映射（RRSM）技術,利用MATLAB對一個矩形貼片天線進行優(yōu)化設計。此外,有源相控陣系統(tǒng)中的改進的校準和優(yōu)化技術將天線波束轉向期望的方向。本文提出的方法和相應的結果如下:（1）在MATLAB 2019b環(huán)境下,采用腔體模型作為粗模型...
