The latest solution for Global Connectivity is Inter-satellite communication. Inter-satellite communication will able to connect two or more satellites directly and hence efficient data transfer is possible with less delay. Choice of frequency is key concern for inter-satellite communication. In this paper, precisely mentioned about importance of millimeter range frequency band for inter-satellite links (ISL) and more focused on the Tapered Slot antenna (TSA) design at 60 GHz. In the design, Substrate Integrated Waveguide SIW feed and corrugation techniques is used to achieve high gain and narrow beam width. Power Divider is used to design two-element TS antenna of 23 dB. For further outlook of antenna design link analysis is also calculated.

Gradient Refractive Index

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.
