Abstract

In this paper, the broadband Fabry‐Perot resonator antenna composed of single‐layer FSS superstrate with dissimilar size square patch fed by U‐slotted patch is proposed, which is validated by two cases of samples. It is demonstrated that the common bandwidth for (3 dB directivity‐drop and −10 dB returned loss of the Fabry‐Perot resonator antenna with the tapered FSS superstrate increases by 7.99% to 12.2% for two different cases, as compared to that of previously single layer FSS with similar size. At the same time the side‐lobe level of antenna can also be improved.The simulated and measured results are good agreement each other. © 2008 Wiley Periodicals, Inc.
