Two Novel Band-notched Uwb Slot Antennas Fed by Microstrip Line
Two kinds of band-notched ultra wide-band slot antennas are proposed. Printed on a dielectric substrate of FR4 with relative permittivity of 4.4 and fed by a 50 Ω microstrip line, the proposed antennas introduce semicircular annular strips to reject the frequency band (5.15–5.85 GHz) limited by IEEE802.11a. The parameters which affect the performance of the antennas in terms of its frequency do...
متن کاملCreating Band-Notched Characteristics for Compact UWB Monopole Antennas
In 2002, the FCC in the US authorized the unlicensed use of the ultrawideband (UWB) frequency spectrum for commercial applications in the range from 3.1 to 10.6 GHz with an emission limit of -41.3 dBm/MHz which is near to the thermal noise floor [1]. UWB communication systems operating in such a wide frequency band and low power emission level could easily be interfered by the existing nearby c...
متن کاملDual and Tri-band-notched Ultrawideband (uwb) Antennas Using Compact Composite Resonators
Abstract—An ultra-wideband (UWB) antenna with triple bandnotched characteristics is presented in this paper. The triple-notched bands (5.15–5.35GHz and 5.725–5.825GHz for WLAN, 7.9–8.395 GHz for X-band) are achieved by using only one novel composite resonator with multiple resonant characteristics. The resonator is placed on the back surface of the substrate and connected to the radiation patch...
متن کاملAn Optimal Design of Cpw-fed Uwb Aperture Antennas with Wimax/wlan Notched Band Characteristics
Abstract—In this paper, a printed slot antenna fed by a co-planar waveguide for ultra wide bandwidth (UWB) with dual notch bands has been presented and discussed. The band notches are realized by etching one C-slot resonator inside a plaque shape exciting stub as well as symmetrically adding a pair of open-circuit stubs at the edge of the slot resulting in dual stop band filtering properties fo...
متن کاملDesign and Time-domain Analysis of Compact Multi-band-notched Uwb Antennas with Ebg Structures
Four ultra-wideband (UWB) antennas are proposed: one referenced antenna without notch and three novel antennas with one, two and three notched bands, respectively. The UWB referenced antenna consists of a beveled rectangular metal patch, a 50 Ω microstrip line and a defective ground plane. Then, by utilizing one, two and three electromagnetic band-gap (EBG) structures on the UWB antenna, the an...
