Butler matrix fed exponentially tapered H-plane horn antenna array system using substrate integrated folded waveguide technology

Abstract

This paper introduces the implementation of 4 × 4 Butler matrix fed antenna array system using substrate integrated folded waveguide (SIFW) technology. The antenna array system generates four directive beams in different angular directions with gain and half power beam width (HPBW) of 6.43, 6.43, 6.33, and 6.43 dB and 12o, 9o, 10o, and 10o. These directive beams will help to suppress the interfering signals from unwanted users, and hence, the quality of high-speed wireless communication will be improved.
