dc.description.abstract | To meet the demand of higher bandwidth Ultra Wide band (UWB) is well known. To suppress newlinethe noise band or interfering band a tunable notch plays an important role. There is some newlinechallenges for an antenna designer like smooth tunablity of notch and uniform radiation newlinecharacteristics in the operating bands. In this work, some possible solutions to the challenges newlineidentified in tunable notch UWB antenna are presented. newlineIn the UWB band, a high-gain Antipodal Vivaldi Antenna for a quad-band notch is newlinedesigned and analyzed. The AVA parameters are first tuned in a simulator to get the desired newlineUWB performance. Sun Shaped Slot and Complimentary Split Ring Resonator devices are used newlineto improve UWB performance as well as for the notched filtering features. As a result, four- newlinenotch bands are observed between 2.2 and 2.7 GHz, 3.3 and 3.6 GHz, 4.6 and 5.7 GHz, and 8.8 newlineand 9.5 GHz. These frequencies are compatible with Bluetooth, WiMax, and WLAN newlinetechnologies, which are ITU applications. The antenna can be used between 1.15 and 14 GHz, newlineexcluding the four elimination bands, according to the measured and projected return loss newlinegraph. The proposed technique allows proper rejection in narrow bands (notch) over the UWB newlineregime. newlineA planar monopole UWB antenna with controllable dual band-notches is presented. In newlinethe proposed antenna, the lower notch (at 3.3 GHz frequency) is realized by cutting one narrow newlinestrip on top of radiating patch whereas the upper notch (at 5 GHz frequency) is obtained by newlineplacing two I-shaped narrow parasitic strips on either side of radiating patch. The tuning from newline3.15 GHz to 3.69 GHz and between 4.93 GHz to 5.59 GHz, is achieved by changing the biasing newlinevoltage of one varactor diode and a pair of other two varactor diodes between 0 V-to-30 V, newlinerespectively. The simulated and experimental results are thus shown to be in good agreement newlinein each of the three cases. The proposed work demonstrates better notch characteristics as newlinecompared with other reported works over the UWB range. newline newline | |
