Abstract

Abstract In this communication, a pyramidal horn antenna is proposed and investigated to operate in the sub-THz region at a centre frequency of 0.245 THz. The antenna has five layers such as coupling layer, air cavity layer, excitation layer, pyramidal horn, and extended side wings. The coupling layer is responsible to couple the electromagnetic (EM) wave from waveguide feed. The excitation layer consists of a plus shape slot which is responsible for the excitation of the proposed antenna. The air cavity is designed such that it can efficiently excite the plus-shaped slot of the excitation layer. In order to achieve high gain and efficiency, the pyramidal horn and the extended side wings are used in combination. The proposed horn antenna has a significant efficiency and gain of 97.1 % and 19.2 dBi respectively and gives a wide impedance bandwidth of 32.3 % (0.205–0.284 THz). When compared to the literature, the proposed novel design demonstrates significant improvement in terms of bandwidth, directivity, and gain. The antenna finds its suitability for Sub-THz 6G wireless communication.

用于 6G 无线通信的次 THz 金字塔形喇叭天线

摘要本文提出并研究了一种金字塔形喇叭天线，该天线可在中心频率为 0.245 太赫兹的亚太赫兹区域工作。该天线有五层，如耦合层、空腔层、激励层、金字塔形喇叭和扩展侧翼。耦合层负责耦合来自波导馈电的电磁波。激励层由一个加形槽组成，负责激励拟议中的天线。气腔的设计使其能够有效地激励激励层的加形槽。为了实现高增益和高效率，金字塔形喇叭和扩展侧翼结合使用。所提出的喇叭天线具有显著的效率和增益，分别为 97.1 % 和 19.2 dBi，并具有 32.3 % 的宽阻抗带宽（0.205-0.284 THz）。与文献相比，所提出的新设计在带宽、指向性和增益方面都有显著改善。该天线适用于亚太赫兹 6G 无线通信。

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.
