Abstract

The past few years have witnessed a surge in the demand for electronic devices capable of operating at high frequencies to achieve faster data transmission, exemplified by the development of the 6G network. Traditional electronic technologies, which were once effective, have now become limited in addressing current requirements due to the increased operating frequencies. In response to this challenge, an innovative solution known as Ridge Gap Waveguide (RGW) technology has emerged. This technology is distinguished by its unique attributes, both in terms of functionality and the construction of electronic devices. It has become a critical focus area for research to tackle the complexities associated with high-frequency communications. This study primarily centers on the design of a directional coupler using RGW technology as its foundational framework. The primary objective of this project has been to create a coupler capable of resolving the inherent issues associated with conventional technologies when operating at higher frequencies. The design process entailed everything from simulating the fundamental structure of an RGW guide to the development of the directional coupler, incorporating the necessary optimizations to enhance its performance. To achieve this objective, a thorough exploration of the theoretical concepts of RGW technology and the principles of directional couplers was conducted. As a result, a coupler with a bandwidth of 1.3 GHz and remarkable return losses of 40 dB was successfully produced. These outcomes serve as a testament to the effectiveness of RGW technology in improving data transmission at higher frequencies. This achievement marks a significant advancement in the capability to design advanced electronic devices that can meet the demands of high-frequency communications in the era of 6G networks.
