Abstract

In this study, the performance of two metamaterial-based antennas – transmit antennas with a double negative index (DNI) and receive antenna with an epsilon near zero (ENZ) material is described for image transfer application. These three-layered antennas are simulated and fabricated on Roger RO3003 substrate. The transmit antenna achieves a gain of 5.5 dBi and a bandwidth of 3.9 GHz, while the receive antenna reports a gain of 11.4 dBi with a 3-dB angular beam width of 32.5° at 5.8 GHz. These antennas are employed with a commercially available transmitter with a camera and receiver. Few images are captured at various distances and simultaneously transferred to the receiver. The images transferred wirelessly are found better in terms of the image quality score obtained using the Blind/Reference less Image Spatial Quality Evaluator (BRISQUE) method, compared to those transferred using the standard dipole antennas. So, the proposed metamaterial-based antennas are suitable for wireless image/video transfer applications.

基于超材料的发射和接收天线，用于 5.8 千兆赫无线图像传输

本研究介绍了两种基于超材料的天线--双负指数（DNI）发射天线和ε近零（ENZ）材料接收天线--在图像传输应用中的性能。这些三层天线是在 Roger RO3003 衬底上模拟和制造的。发射天线的增益为 5.5 dBi，带宽为 3.9 GHz；接收天线的增益为 11.4 dBi，在 5.8 GHz 时的 3 dB 角波束宽度为 32.5°。这些天线与带有摄像头和接收器的市售发射机配合使用。在不同的距离拍摄少量图像，并同时传输到接收器。与使用标准偶极子天线传输的图像相比，使用盲/少参考图像空间质量评估器（BRISQUE）方法获得的图像质量得分显示，无线传输的图像质量更好。因此，拟议的超材料天线适用于无线图像/视频传输应用。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
