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.

AbstractConformal transformation optics is employed to enhance an H-plane horn’s directivity by designing a graded-index all-dielectric lens. The transformation is applied so that the phase error at the aperture is gradually eliminated inside the lens, leading to a low-profile high-gain lens antenna. The physical space shape is modified such that singular index values are avoided, and the optical path inside the lens is rescaled to eliminate superluminal regions. A prototype of the lens is fabricated using three-dimensional printing. The measurement results show that the realized gain of an H-plane horn antenna can be improved by 1.5–2.4 dB compared to a reference H-plane horn.
