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. Gain Enhancement of a Wide Slot Antenna Using a Second Gain enhancement of a wide slot antenna over a wide frequency band using a low profile, second order bandpass frequency selective surface (FSS) as a super-strate is presented in this paper. The proposed multilayered FSS with non-resonant unit cells in each layer allows in-phase transmission of waves radiated from the antenna 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.
