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.

商品描述(中文翻譯)

在近年來,傳輸陣列天線(transmitarray antennas)引起了越來越多天線研究者的關注。傳輸陣列結合了光學和天線陣列理論,實現了低剖面設計,具備高增益、高輻射效率以及多樣化的輻射性能,適用於許多無線通信系統。本書介紹了傳輸陣列天線的綜合分析、新方法論和新穎設計。

- 本書詳細分析了平面空間供電陣列天線的設計。描述了孔徑場分佈的基本原理以及陣列元件的分析。使用陣列理論方法討論了輻射性能(指向性和增益),並展示了元件相位誤差的影響。
- 小心研究了使用多層頻率選擇表面(multilayer frequency selective surfaces, M-FSS)方法的傳輸陣列設計性能,揭示了傳輸相位限制通常與特定元件形狀的選擇無關。最大傳輸相位範圍根據層數、基板介電常數和層間距離確定。
- 為了降低傳輸陣列設計的複雜性和成本,研究了三種不同的方法。因此,使用無介電材料的四層交叉槽元件進行了一種設計,另一種則使用三層螺旋偶極元件。這兩種設計均在X波段進行了製作和測試,適用於深空通信。此外,還研究了在不同供電極化條件和從供電處入射場的斜角下的輻射模式特性。
- 提出了新的設計方法論,以通過控制元件的傳輸相位範圍來改善傳輸陣列天線的帶寬。這些設計技術通過在Ku波段製作和測試兩個四層傳輸陣列天線得到了驗證。
- 研究、設計、製作並在Ku波段測試了一個單供電四束傳輸陣列天線,束間的仰角分離為50度。

總之,本書針對傳輸陣列天線的分析和設計中的各種挑戰進行了探討。展示了改善傳輸陣列天線帶寬的新方法論。製作並測試了幾個原型,顯示了傳輸陣列天線的理想特性和潛在的新應用。
