SIW Dual Mode Compact Filtenna for 6G Technology

This paper introduces a compact Transverse Magnetic (TM) dual-mode Filtenna design, implemented on a printed circuit board (PCB) to reduce the size compared to conventional waveguide designs, this Filtenna also allows for easier integration with other components. Non-resonating nodes (NRNs) are employed to enhance selectivity and improve out-of-band rejection. The design achieves a realized gain of 4.3 dBi, making it a promising, space-efficient filtering solution for modern communication systems. Fabrication results are provided to validate the performance of the proposed Filtenna.
