Abstract

In this paper, a substrate-integrated waveguide (SIW) H-plane horn antenna has been designed for X-band applications. Metamaterial is incorporated for performance enhancement of the designed antenna. Capacitively loaded loop is used as the unit cell of metamaterial for achieving negative values of relative permittivity and relative permeability. A half-mode SIW H-plane horn antenna is also proposed in this paper which reduces the size of the antenna without much effect on its performance. Metamaterial is integrated on the half-mode horn as well for improvement in gain and radiation pattern. The antennas are fabricated and tested. Excellent agreement between the measured and simulated results was obtained.
