Fabry-Perot Resonator Antenna

Fabry-Perot Resonator (FPR) antennas have attracted significant attention in microwave and millimeter waves due to a number of attractive properties, such as low complexity, high directivity and conformal deployment capability. In this paper, a summary of recent publications on FPR antenna is presented focusing on the different capabilities, technologies and architectures that have been proposed. Several structures, analytic models and research developments and a corresponding comparison are also made. It shows that such analytic models as FP cavity model, EBG defect model, transmission line model, leaky wave model and refractive lens model are consistent when applied to analyze this type of resonator antenna. Some interesting topics under recent research are surveyed in detail. At the same time some attractive topics to be further researched are also pointed out. Recent works of the authors are also included in this paper.
