Broadband Coplanar Waveguide - Fed Wide - Slot Antenna
A large bandwidth wide-slot antenna, fed by coplanar waveguide (CPW), is proposed. Experimental investigations and detailed simulations are conducted to understand its behavior and to optimize for broadband operation. The impedance bandwidth, determined by 10-dB return loss of the proposed slot antenna using both measurement and simulation, is about 131% (2.8 to 14GHz). In addition to be small ...
متن کاملImprovement the reflection coefficient of Waveguide-Fed Phased-Array Antenna utilizing Liquid Crystal
Abstract— This work investigates the improvement of the active reflection coefficient of waveguide-fed phased-array antenna using liquid crystal layers. The anisotropy properties of liquid crystal layer can be employed to eliminate blind scan angle and improve the wide angle impedance matching of the waveguide-fed phased array antennas. The authors have expressed the modal analysis of the waveg...
متن کاملCoplanar Waveguide-fed RectangularSlotAntennafor Ultra-Wideband Application
This study describes a tunable coplanar waveguide fed (CPW) rectangularslot antenna to work within ultra wide band (UWB) for the future communication systems. This slot antenna of area 30*20mm is designed on a FR4 substrate and its operation was tested in terms of return loss and gain. The developed antenna shows VSWR 2 bandwidth of 800MHz in 0.7-1.51GHzband as well as bandwidth of 6.06GHz in...
متن کاملA Coplanar Waveguide Fed Hexagonal Shape Ultra Wide Band Antenna with WiMAX and WLAN Band Rejection
In this paper, a coplanar waveguide (CPW) fed hexagonal shape planar antenna has been considered for ultra-wide band (UWB). This antenna is then modified to obtain dual band rejection. The Wireless Local Area Network (WLAN) and Wireless Microwave Access (WiMAX) band rejections are realized by symmetrically incorporating a pair of L-shape slots within the ground plane as well as a couple of I-sh...
متن کاملCoplanar Waveguide-fed Ultra-wideband Planar Antenna with WLAN-band Rejection
A compact coplanar waveguide (CPW)-fed ultrawideband (UWB) antenna is proposed with band-notched characteristic. The antenna has compact size of 29 x 31 mm 2 . A novel wide polygon-slot is inserted on the antenna to obtain good impedance matching and wide bandwidth. A tapered radiating patch is placed inside the polygon-slot. An embedded C-slot in the radiating patch avoids potential interferen...
