Abstract

An analysis of phase variation and phase range of concentric split ring square element for broadband reflectarray antenna is presented in this paper. This element is the combination of a splitted single square and ring element whereas the square element is the modification of the conventional annular ring in which, instead of using annul as the hole, this new idea presents a square as the hole in the ring. This will modifies the current distribution in the element which will then improve the performance of the bandwidth as the objective of this work. The physical interpretation of the elements is presented and variety of frequency responses pattern is described and analysed. The design procedure and critical parameters consist of phase range and phase slope (or variation) are also discussed. The proposed antenna element effectively covers two frequency operations (13.44 GHz and 18.36 GHz) in Kuband range. Bandwidth broadening is achieved by introducing the ring square combination of element and the practical phase range is achieved through the use of RF35 (thickness = 1.524 mm) as the substrate. The new concept of split initiates to a wider bandwidth (up to 67.6%) for the antenna and can applied to any two frequency operations of Ku-band applications.
