UWB Band Pass Filter with WLAN notch
In this paper, UWB technology operating in broad frequency range of 3.1-10.6 GHz has shown great achievement for highspeed wireless communications. to satisfy the UWB system requirements, a band pass filter with a broad pass band width, low insertion loss, and high stop-band suppression. UWB band-pass filter (BPF) with wireless local area network (WLAN) notch at 5.8 GHz and 3-dB fractional band...
متن کاملDesign of UWB Filter with Notch Band for WLAN (5.3-5.8 GHz) Signal Interference Rejection
In this letter, a design of Compact Ultra-Wideband (UWB) bandpass filter with a switchable notch band for WLAN (5.3-5.9GHz) interference rejection is proposed. As 5.3-5.9GHz wireless local area network (WLAN) is existed in UWB spectrum range (3.1 -10.6GHz) and may interfere with UWB system operation. The UWB bandpass filter is implemented using a basic multiple mode resonator (MMR) structure fe...
متن کاملUWB CIRCULAR SLOT ANTENNA PROVIDED WITH AN INVERTED-L NOTCH FILTER FOR THE 5 GHz WLAN BAND
Abstract—The study of a planar circular slot antenna for Ultrawideband (UWB) communications is presented. The integration on this antenna of a notch filter, to reduce the possible interferences with the 5GHz WLAN communications, has been discussed in detail. Four different structures, achieved by etching a suitable pattern on the antenna circular stub, have been considered, and their features h...
متن کاملUWB printed monopole antenna with a notch frequency for coexistence with IEEE 802.11a WLAN devices
In this paper, we have investigated a printed modified circular disc monopole antenna with cross-shaped slot in radiating patch for UWB applications. The proposed antenna covers the entire UWB band (i.e., 3.1GHz to 10.6GHz) except the frequency band of IEEE 802.11a (i.e., from 5.15GHz to 5.83GHz). This UWB antenna will be of use in environments where IEEE 802.11a WLAN devices are already in ope...
متن کاملDesign of A Compact CPW-FED UWB Antenna with WiMAX and WLAN Band-Notched Characteristic Evaluated in AHP Framework
In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators. The proposed antenna can operate from 2.82 to 11 GHz (118%), defined by VSWR< 2, except two notched bands around 3.5 GHz (WiMAX) and 5.5 GHz (WLAN)...
