Dielectric Sheets Covered Broadband Vivaldi Antenna for Gain Enhancement

Abstract: Abstract-To enhance the gain of conventional Vivaldi antenna (CVA), a novel dielectric sheets-covered Vivaldi antenna (DSCVA) is proposed. The dielectric sheets suck energy from the tapered slot region and flare termination region of the CVA, and thus act as surface wave antennas to improve end-fire performances. The CVA, DSCVA as well as the DSCVA with elongated tapered profile (SP-DSCVA) are designed, fabricated and measured. The simulation results are in good agreement with the experimental data. Measuremen… Show more

“…Table listed a comparison between proposed antenna and previously reported related articles. When the proposed antenna compared with those in References 5–9, 11, and 13, then it provides higher gain than these and in terms of compactness, it is much more compact than those in References 5, 7, 8, and 13. It is also seen that the bandwidth of the proposed antenna is wider than those in References 2, 5–9, 11, and 13.…”

“…Dielectric slabs of different shapes show little effect on the performance of the CAVA at high frequency. To achieve better performance, the fractal shape is used on the dielectric slabs because due to space‐filling properties of the fractal, it enlarges the electrical length of the dielectric slab without involving additional physical area .…”
