A UWB antenna combined with the crlh metamaterial UWB bandpass filter having the bandstop at the 5 GHz-band Wlan

Abstract

This paper investigates how a Ultrawide Band(UWB) antenna can get the stopband created by the UWB filter which has a notch at the 5 GHz-band WLAN(Wireless Local Area Network) service. Particularly, we proposed the design of the Composite Right- and Left-Handedness(CRLH) metamaterial UWB notched-bandpass filter to have the smallest component possible connected to the feedline of the UWB antenna. We will see the A/9long UWB filter with and without the notch, and the acceptable VSWRs of the UWB antenna before and after being combined with the notched metamaterial UWB filter.
