The study reviewed mechanically reconfigurable reflectarray (RA) and transmitarray (TA) antennas, categorizing them into three major groups and a hybrid category. Performance metrics such as aperture efficiency, gain, bandwidth, scanning range, and resolution were compared across different approaches. Opportunities for further advancements in antenna performance were also identified.
We review mechanically reconfigurable reflectarray (RA) and transmitarray (TA) antennas. We categorize the proposed approaches into three major groups followed by a hybrid category that is made up of a combination of the three major approaches. We discuss the examples in each category and compare their performance metrics including aperture efficiency, gain, bandwidth and scanning range and resolution. We also identify opportunities to build upon or extend these demonstrated approaches to realize further advances in antenna performance.
