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× 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.

We report on the full-wave analyses of a frequency reconfigurable antenna integrated with metallic nanoelectromechanical system (NEMS) switches (length ¼ 3 lm, width ¼ 60 nm). The NEMS switch used in this work has the same architecture with low voltage, double-arm cantilever-type metallic DC-contact microelectromechanical system (MEMS) switch recently developed in author's group. The microfabrication and characterization of the MEMS switch have also been given in this article.
