Design of UWB Microwave Filter Using Quarter Wavelength Short-Circuited Stub
Abstract: UWB technology has progressed a lot in recent years for high speed wireless communications and other applications which need higher data rate and wider bandwidth. In this paper UWB bandpass filter is designed using quarter wavelength (λ0/4) short circuited stubs to improve the performance of UWB. Designed UWB filter gives higher performance and lower insertion loss in UWB spectrum. 5th order UWB bandpass filter is designed using CST MWS simulation …

Compact Printed Coplanar Waveguide-fed UWB/Bluetooth Integrated Antenna for Wireless Personal Area Network Communication
Abstract: AbstractA compact integrated Bluetooth and ultra-wideband (UWB) coplanar waveguide (CPW)-fed antenna is presented and discussed. In this paper, the designed antenna has got specialty having wide coverage of Bluetooth and UWB frequency band both successfully giving optimum performance and above all small size. It has been designed very compact retaining all the standard parameters like VSWR, radiation pattern and gain to the acceptable level. The integrated dual-band antenna covering 2.4–2.484 …
