چکیده
|
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). the size of the antenna is 20×20×1.6 mm3. the experimental and simulated results of the prototyped antenna, including voltage standing wave ratio (vswr), radiation pattern, and gain characteristics are presented and discussed. in addition, analytical hierarchy process (ahp) method used for comparison the proposed antenna with previous designed structures.
