Novel Unidirectional Slot Antenna With a Vertical Wall

Abstract: Abstract-A novel slot antenna that consists of an H-shaped slot encompassed by a rectangular metallic wall and a pair of C-shaped slots outside the wall is proposed. It features a unidirectional pattern, small electrical dimensions and medium gain. The H-shaped slot radiates as an inductively loaded magnetic dipole while the induced electric currents on the vertical wall radiates as electric dipoles. The front-to-back ratio (FBR) of the antenna can be controlled by proper constructive and destructive interfere… Show more

“…Hence, they need to be integrated with a reflector to achieve directional radiation characteristic [4,5]. It was reported that the metal cavity reflector had been used to provide directional patterns [6], but this kind of antenna is not convenient to use because of its large size.…”

“…Techniques have been used to provide directional radiation patterns, such as using the metal cavity reflector [6][7][8]. Directional radiation patterns have been implemented using Electromagnetic Bandgap (EBG) structures [9,10], but these investigations only consider a single operating frequency.…”
