Abstract
In this article, a novel design of ultra wideband monopole antenna with dual notched bands performance is proposed. The size of the UWB antenna is minimized to 20 -17.6mm2 , printed on FR4 substrate 1.5 mm thickness and loss tangent tan𝛿 =0.02, and is fed by coplanar waveguide. The operation bandwidth of the designed antenna is from 3.1 GHz to more than 10 GHz. Band notches characteristics of antenna to reject the frequency band, WIMAX Band and WLAN Band, is realized by cutting three quarter wavelength slots in the radiating patch. A quarter wavelength slot in the radiator of the antenna is used to create a frequency band notch at the WIMAX frequency band. However, the WLAN frequency band is notched using two symmetrical quarter wavelength slots. The proposed antenna is simulated using HFSS and CST high frequency simulators. These results are compared with measured results by using network analyzer.
Highlights
Due to the progress in wireless communication systems and the increase in their applications, ultra-wideband (UWB) technology has recently become one of the most fascinating advancements for high transmission rate indoor and outdoor wireless communications, and for low power consumption
There are many methods with which we can achieve a band notch characteristic in UWB antenna [5,6,7,8,9,10,11,12,13,14]. Another method to generate the band notched function is to put in parasitic elements [15], and a split ring resonator (SRR) type slot has been embedded on the patch to obtain notch characteristic at WLAN and WIMAX [16]
We propose a simple method to realize the dual band notched characteristics for a compact UWB monopole antenna, using only triple straight slots etched in the radiator patch
