Integrated triple notch bands compact UWB antenna for wireless communications

Abstract

To Suppress Conventional Narrow Band Communication Technologies From The UWB Frequency Band An Integrated Triple Notch Bands Compact UWB Antenna Is Proposed. Band Notches Are Wimax (3.1-3.8 Ghz),WLAN(4.8-5.825 Ghz) And X Band (6.5-7.5 Ghz).To Attain UWB Frequency Band 2.9-14.5 Ghz From Compact UWB Antenna Introduced Slots In A Rectangular Patch With DGS. The Projected Compact UWB Antenna Arrangement Is Made-Up On FR4 Substrate With VSWR Is Less Than 2 Except For Selected Notched Bands. The Proposed UWB Design Is Suitable For Impenetrable Surroundings For Wimax/WLAN/X Band Dense. The Partial Defective Ground Structure Is Proposed To Improve Impedance Matching And Impedance Bandwidth Is Utilized.
