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.
