Abstract

With the widespread adoption of electronics, there is an increasing demand for wireless alternatives for various products. This increase is evident in smaller devices like headsets, prompting the need for antenna development specific to such compact designs. This project focuses on designing an antenna specifically for a small wireless headset, leveraging the mechanical specifications of the RTX A/S RTX8950 model. Prototypes are designed, simulated and measured to assess the correlation between simulation and measurement to improve on the simulation model and optimise the antennas. The antennas were utilised for the development of the double antenna PCBs. The selected prototypes demonstrated high gain upon measurement, yet it still requires slight matching adjustments to fully meet the return loss requirement. While the double antenna PCBs were not measured, simulations indicate promising results. However, there is a need to reduce the coupling between the antennas, given the power of the s12 in the simulations.
