The present study introduces a small and efficient antenna designed specifically for medical implants. With the increasing demand for wireless and minimally invasive medical devices, there is a need for antennas that can reliably transmit and receive data within the human body. The antenna presented in this study functions within the Industrial, Scientific, and Medical (ISM) frequency band, meeting all necessary regulations with a size of 10×10×1.6 mm$^3$. FEM-based HFSS software has been used for simulation and using Roger 3010 substrate with relative permittivity of 10.2. We carefully selected materials and used optimization techniques to create a compact design without sacrificing perfo... More >

This paper presents the design of a wideband cavity-structure transverse slot antenna based on a substrate integrated waveguide (SIW) for fifth-generation (5G) applications. The antenna is specifically engineered to cover the European 5G frequency range (24.25 – 27.5 GHz). By strategically positioning multiple resonant slots on the bottom metal cladding of the SIW cavity, hybrid modes are generated within the desired frequency band. The characteristics of these modes can be adjusted by altering the slot parameters, resulting in the merging of wideband resonance frequencies. Simulation results demonstrate a bandwidth of 3.3 GHz (13.58%), spanning from 23.5 GHz to 26.8 GHz, with a gain of 10... More >
