Integrated bluetooth and UWB antenna

This paper presents a microstrip-fed integrated bluetooth and ultra-wide band (UWB) antenna that is small, low-profile, and planar. Antenna occupies an area of 42 times 46 (mm) on a printed circuit board (PCB). The design of the antenna is optimized to provide high performance for the operation at 3100-10600 MHz (UWB) and 2400-2484 MHz (bluetooth) bands. The antenna was fabricated and its return loss and radiation patterns were measured and compared to the simulations results showing a good agreement between theoretical and measured results.
