The gain of a slot antenna can be increased with the help of a single layer metamaterial superstrate. Metamaterial is used because they have negative index of refraction and it has the ability to bend light back towards the source. Keywords: zero refractive index, metamaterials, gain enhancement, patch antenna. Wideband gain enhancement of slot antenna using one ... A quarter-wavelength-thick unprinted dielectric slab is placed above a slot antenna to achieve high gain with a large bandwidth. By optimally truncating the high-permittivity superstrate to a small area of 2.25λ0 2, 8–10 dB enhancement in the directivity of the slot is achieved over a 3 dB directivity bandwidth of 16–18%. Gain Enhancement of 60-GHz Antipodal Tapered Slot Antenna ... Abstract: A zero-index metamaterial (ZIM) structure is proposed for the gain enhancement of an antipodal tapered slot antenna (ATSA) at 60-GHz bands. The single ATSA loaded with the proposed ZIM cells exhibits a gain enhancement of up to 2.6 dB in the frequency band of 57-66 GHz. Gain enhancement of annular slot antennas - IET Journals ... Abstract: The gain enhancement of an annular slot antenna fed by a cavity is studied numerically. The method of moments for bodies of revolution is used as a numerical tool for the simulations. The effect of different parameters is investigated and methods for gain enhancement are proposed.
