Communication technology is constantly evolving to meet the evolving needs of modern communication. Massive multiple-input multiple-output (mMIMO) technology has become the global standard for fifth-generation (5G) communication systems. Cell-free massive MIMO (CF-mMIMO) is a key technology for beyond fifth-generation (B5G) networks. The radio stripe network (RSN) is a concept that can make CF-mMIMO systems possible. RSN systems are distributed over a stripe, making deployment and transit easier. To make RSN system deployment and transit easier, low-cost, low-profile, and flexible microwave passive devices, including antennas for radio stripes, are required. Surface Plasmon Polaritons (SPPs) are surface waves that are highly confined and travel over the metal-dielectric interface. They can be transmitted by treating the corrugated metal surface as a unit cell of a periodic structure. SSPP technology is a compact, low-cost, and easy-to-fabricate platform that can meet future wireless communication demands due to their strong field confinement and groundless structure. SSPP structures also have advantages like resistance to electromagnetic interference and controllable dispersion behavior. This makes SSPP technology a suitable platform for designing passive microwave devices, including antennas, that can satisfy the demands of B5G RSN applications. The aim of this project is to develop passive microwave devices and antennas for RSN applications.
