This bachelor's thesis deals with the design of an antenna for Channel Sounding technology intended for integration into a smartphone. The antenna is designed for the 2.4 GHz frequency band used by Bluetooth Low Energy technology. The thesis first compares selected antenna topologies suitable for this application and subsequently analyzes optimization methods available in ANSYS HFSS and Optimetrics. The main part of the thesis is focused on the design, modification, and optimization of a meander slot antenna. During the design process, several modifications of the antenna geometry, substrate material, and resistive loading were carried out in order to achieve the required impedance matching within the Bluetooth Low Energy band. The final antenna design was fabricated and experimentally verified by impedance matching and radiation pattern measurements. The measured results were compared with simulations, and the proposed antenna was subsequently compared with a reference PIFA antenna.
