Abstract
A wideband high-efficiency dual-polarized metal-only reflectarray antenna is designed and analyzed. The unit cell is composed of a layer of grooved metal plate and a ground, with an air layer in the middle. The proposed element features a phase range of about 360° and works independently in orthogonal directions, enabling dual linearly polarized operations. Based on this unit cell, a circular array including 177 elements with a diameter of 250 mm is simulated and fabricated at 10 GHz. The measured results show that the reflectarray exhibits a good performance in both horizontal and vertical polarizations, with a 1-dB gain bandwidth of 20.2% and 20% and peak aperture efficiency of 62.3% and 61%, respectively. In addition, sidelobe and cross-polarization levels are also satisfactory.
期刊介绍：
International Journal of RF and Microwave Computer-Aided Engineering provides a common forum for the dissemination of research and development results in the areas of computer-aided design and engineering of RF, microwave, and millimeter-wave components, circuits, subsystems, and antennas. The journal is intended to be a single source of valuable information for all engineers and technicians, RF/microwave/mm-wave CAD tool vendors, researchers in industry, government and academia, professors and students, and systems engineers involved in RF/microwave/mm-wave technology.
Multidisciplinary in scope, the journal publishes peer-reviewed articles and short papers on topics that include, but are not limited to. . .
-Computer-Aided Modeling
-Computer-Aided Analysis
-Computer-Aided Optimization
-Software and Manufacturing Techniques
-Computer-Aided Measurements
-Measurements Interfaced with CAD Systems
In addition, the scope of the journal includes features such as software reviews, RF/microwave/mm-wave CAD related news, including brief reviews of CAD papers published elsewhere and a "Letters to the Editor" section.
