Short Course Abstract

In the recent years, reflectarrays have emerged as the new generation of high-gain antennas which have attracted an increasing interest in the antenna/electromagnetic community because of their low-profile, low-mass, and low-cost features. The reflectarray antenna is a hybrid design, which combines the many favorable features of reflectors and printed arrays, and offers many notable advantages over these two classic high-gain antennas. The aim of this short course is to present a comprehensive overview of reflectarray system design and state-of-the-art technology. This short course will enable attendees to understand the basics of reflectarray systems, become familiar with reflectarray design, analysis techniques, and enabling technologies, and correctly apply this knowledge to designing reflectarrays for diversified applications. Based on the authors’ forthcoming book on reflectarray antennas, this short course is available in a half-day format presenting nearly 200 slides.


Short Course Outline

This proposed curriculum for this course will be offered in two parts. In the first part, the history of reflectarray antenna development is first reviewed and then basic theories for analysis and design of reflectarray antennas are presented in detail. This section of the course builds the fundamental knowledge one needs to have in order to understand the governing dynamics of a reflectarray antenna system, and efficiently design and analyze reflectarray antennas. The second part of the course is intended for researchers that have a good knowledge of the basic theories in reflectarray, and aim at designing reflectarray antennas for specific applications/operations. This part starts with a discussion on bandwidth limitation and solutions for broadband designs, and afterwards several advanced application oriented topics in reflectarray antennas will be presented. More in detail, the following material will be presented in this short course.


Part I: Basics of Reflectarray Antennas

  • Introduction and Reflectarray History
  • Analysis and Design of Phasing Elements
  • Aperture Efficiency Analysis
  • Radiation Analysis, Pattern Calculation, Loss Budget
  • Practical Design Examples


Part II: Advanced Topics on Reflectarray Antennas

  • Bandwidth of Reflectarray Antennas
  • Multi-Band and Wideband Reflectarray Antennas
  • Multi-Beam and Shaped-Beam Reflectarray Antennas
  • Beam-Scanning Reflectarray Antennas
  • Advanced Configurations (THz/IR, and non-planar reflectarrays)


In summary, the proposed short course will effectively provide the attendees with fundamental capabilities and skills required for a researcher in the field of reflectarray antennas. These are tabulated below.

  • An overview of the reflectarray antenna research history, including various implementations and state-of-the-art.
  • Basic theories for design and analysis of reflectarray antennas, which will help to build up the fundamental capabilities for reflectarray research along with a wealth of design examples that can serve as a good reference for the attendees.
  • Design procedures for a wide range of diversified applications, such as broadband designs, multi-band operation, multi-beam performance, beam-scanning systems, and conformal reflectarray antennas, along with illustrative examples for each design.
