Small aperture radial waveguide slot array antenna design for indoor Bluetooth application

The radial waveguide slot array (RWSA) antenna is known for its good characteristics such as low profile, low cost, aesthetically pleasing, ease of installation and simple structure. This research project involves the design and development of the novel linearly polarized small aperture radial waveguide slot array (RWSA) antenna for indoor Bluetooth applications operating based on ISM frequency band standard, with frequency range of 2.4-2.4835 GHz. Zeland Fidelity 4.0, an FDTD based antenna simulation is utilized to estimate the input impedance and radiation pattern of the antenna design. The second part of this project includes the antenna prototypes fabrication and experimental evaluation. Finally, the measurement analysis is compared with the theoretical result.
