Abstract

In this paper, a single-layer reflectarray design is presented for X-band applications. The reflectarray comprises of pie-shaped reflective elements. The unit element has compact dimensions of 0.28λo × 0.28λo. The major segment angle of pie-shaped element controls the reflection phase range and offers a total of 650º phase variation. A reflectarray prototype comprising 23 × 23 elements is realized to demonstrate the necessary reflection characteristics. Different parameters are analyzed for performance evaluation of the reflectarray. The proposed
reflectarray offers measured gain of 24 dBi with 1-dB and 3-dB gain bandwidth of 18% and 28% respectively. Moreover, side-lobe-levels and cross-polarizations are less than 22 dB and 35 dB respectively.
