High Gain Tapered Slot Antenna
Aug 10, 2019 A broadband high gain Tapered slot antenna array for under water communication is presented in this paper. The procedure to design the unit element antenna is followed by applying a linear tapered array-slot structure to the conventional Vivaldi antenna; hence the bandwidth, gain and radiation efficiency of the antenna are improved. Tapered slot antennas loaded with different unit layouts were designed. The result comparison showed that after the layout optimisation, the operation frequency band with a gain above 10 dB increased by about 13% and the gain increased by 0.4–2.6.
Current ultra-wide bandwidth (UWB) and high-gain antennas include mainly log-periodic antenna, traditional transverse electromagnetic (TEM) horn antenna, spiral antenna, bow-tie antenna, tapered slot antenna, and microstrip patch antenna. However, the traditional Yagi antenna and microstrip patch antenna have narrow bandwidth.

Abstract
A broadband gradient refractive index (GRIN) metamaterial is used to improve the gain of the tapered slot antenna. The proposed metamaterial is capable of reducing the side lobe level of the antenna. The gradient refractive index (GRIN) metamaterial is constructed by using non-resonant parallel-line unit cells with different refractive index. Due to the non-resonant structure, the proposed unit cell exhibits low loss and large frequency bandwidth. The metamaterial, whose effective refractive index is lower than that of the substrate on which the antenna is printed. Therefore, the proposed metamaterial is act as a regular lens in beam focusing. The GRIN metamaterial is integrated in front of the antenna which has the capability to manipulate electromagnetic wave accurately. The measurement results indicate that the reflection coefficient of the antenna is below -10 dB over the frequency band from 3 to 11 GHz. The radiation pattern of the antenna shows the beam width becomes narrow and directive with low side lobe level. The peak gain is increased by 2.1 dB at 9.5 GHz.
