Compact Wearable Bluetooth Antenna

In recent years, demand for small antennas in wireless communication has rapidly increased. Antenna plays a major role in wireless systems. Antenna works with great efficiency only in certain range of frequencies, this means that the design of antenna greatly impacts the overall performance of wireless system. Most of the applications using radio communication are not secure and reliable. This can be overcome by using Bluetooth. For a Bluetooth connection to be well established, efficient antenna is required. This project is a step towards improving performance of the Bluetooth antenna, thus improve the overall efficiency of wireless systems. This Bluetooth antenna is designed using HFSS software with FR4 epoxy as substrate. The simulated antenna will be operating at resonant frequency of 2.47 GHz, which is also the frequency range for a Bluetooth communication. Good gain and directivity can be obtained using this Bluetooth antenna which is desirable for wearable communication devices in military application.
