商品描述

In recent years, transmitarray antennas have attracted growing interest with many antenna researchers. Transmitarrays combines both optical and antenna array theory, leading to a low profile design with high gain, high radiation efficiency, and versatile radiation performance for many wireless communication systems. In this book, comprehensive analysis, new methodologies, and novel designs of transmitarray antennas are presented.

 

  • Detailed analysis for the design of planar space-fed array antennas is presented. The basics of aperture field distribution and the analysis of the array elements are described. The radiation performances (directivity and gain) are discussed using array theory approach, and the impacts of element phase errors are demonstrated.
  • The performance of transmitarray design using multilayer frequency selective surfaces (M-FSS) approach is carefully studied, and the transmission phase limit which are generally independent from the selection of a specific element shape is revealed. The maximum transmission phase range is determined based on the number of layers, substrate permittivity, and the separations between layers.
  • In order to reduce the transmitarray design complexity and cost, three different methods have been investigated. As a result, one design is performed using quad-layer cross-slot elements with no dielectric material and another using triple-layer spiral dipole elements. Both designs were fabricated and tested at X-Band for deep space communications. Furthermore, the radiation pattern characteristics were studied under different feed polarization conditions and oblique angles of incident field from the feed.
  • New design methodologies are proposed to improve the bandwidth of transmitarray antennas through the control of the transmission phase range of the elements. These design techniques are validated through the fabrication and testing of two quad-layer transmitarray antennas at Ku-band.
  • A single-feed quad-beam transmitarray antenna with 50 degrees elevation separation between the beams is investigated, designed, fabricated, and tested at Ku-band.

 

In summary, various challenges in the analysis and design of transmitarray antennas are addressed in this book. New methodologies to improve the bandwidth of transmitarray antennas have been demonstrated. Several prototypes have been fabricated and tested, demonstrating the desirable features and potential new applications of transmitarray antennas.

近年來,傳輸陣列天線引起了許多天線研究人員的關注。傳輸陣列結合了光學和天線陣列理論,實現了低輪廓設計、高增益、高輻射效率和多功能輻射性能,適用於許多無線通信系統。本書介紹了傳輸陣列天線的全面分析、新方法論和創新設計。

本書首先詳細分析了平面空間餵入陣列天線的設計。介紹了孔徑場分佈的基礎知識和陣列元素的分析。使用陣列理論方法討論了輻射性能(指向性和增益),並演示了元素相位誤差的影響。

其次,本書仔細研究了使用多層頻率選擇表面(M-FSS)方法設計傳輸陣列的性能,揭示了傳輸相位限制通常與特定元素形狀的選擇無關。根據層數、基板介電常數和層間距離確定了最大傳輸相位範圍。

為了降低傳輸陣列的設計複雜性和成本,本書研究了三種不同的方法。結果,一種設計使用無介電材料的四層交叉槽元素,另一種使用三層螺旋偶極元素。這兩種設計在X頻段進行了製作和測試,並研究了在不同餵入偏振條件和餵入場的斜角下的輻射特性。

本書提出了改善傳輸陣列天線頻寬的新設計方法。通過控制元素的傳輸相位範圍,驗證了這些設計技術。在Ku頻段製作和測試了兩種四層傳輸陣列天線,驗證了這些技術的有效性。

本書還研究、設計、製作和測試了一種Ku頻段的單餵入四波束傳輸陣列天線,波束之間的仰角分離為50度。

總之,本書解決了傳輸陣列天線分析和設計中的各種挑戰。展示了改善傳輸陣列天線頻寬的新方法論。製作和測試了多個原型,展示了傳輸陣列天線的理想特性和潛在新應用。
