Wideband reflectarray antenna using stub-loaded inverted E elements for Ku-band applications

EasyChair Preprint 1896

Abstract

This paper presents the design and experimental evaluation of a wideband reflectarray antenna using stub-loaded inverted E elements. A reflectarray of size 200 × 200 mm2 with 18 x 18 such elements is fabricated and measured for its radiation patterns. Through simulation-based study, two optimal gain-bandwidth performances are shown to be achievable by varying the focal distance and inter-element spacing values. In case 1, a 3-dB gain-bandwidth of 40% is observed with a peak gain and an aperture efficiency of 23.6 dBi and 28%, respectively. In case 2, a 2-dB gain-bandwidth of 32% is noted with a peak gain of 25.2 dBi and an aperture efficiency of 42%.
