商品描述

The aim of this book is to present the modern design principles and analysis of lens antennas. It gives graduates and RF/Microwave professionals the design insights in order to make full use of lens antennas.  Why do we want to write a book in lens antennas? Because this topic has not been thoroughly publicized, its importance is underestimated. As antennas play a key role in communication systems, recent development in wireless communications would indeed benefit from the characteristics of lens antennas: low profile, and low cost etc.
 
The major advantages of lens antennas are narrow beamwidth, high gain, low sidelobes and low noise temperature. Their structures can be more compact and weigh less than horn antennas and parabolic antennas. Lens antennas with their quasi-optical characteristics, also have low loss, particularly at near millimeter and submillimeter wavelengths where they have particular advantages.

This book systematically conducts advanced and up-to-date treatment of lens antennas.

商品描述(中文翻譯)

本書的目的是介紹現代鏡頭天線的設計原則和分析方法,為畢業生和射頻/微波專業人士提供設計洞察,以充分利用鏡頭天線。為什麼我們要寫一本關於鏡頭天線的書呢?因為這個主題尚未得到充分宣傳,其重要性被低估了。由於天線在通信系統中起著關鍵作用,無線通信的最新發展確實可以從鏡頭天線的特性中受益:低輪廓、低成本等等。

鏡頭天線的主要優勢包括狹窄的波束寬度、高增益、低旁瓣和低噪聲溫度。它們的結構比喇叭天線和抛物面天線更緊湊、更輕巧。鏡頭天線具有類光學特性,尤其在毫米波和亞毫米波長處,具有特殊的優勢,損耗低。

本書系統地進行了鏡頭天線的高級和最新處理。
