| Popis: | This study presents a systematic design method for a conical-type monopole antenna exclusively for use in an ultrawide band (UWB). The suggested antenna adopts a structure called the split ring resonator (SSR), in which one resonant element can be easily attached and detached. It is possible to adjust the size of the SSR and the gaps; this SSR, operating at the relevant frequency, can be attached to and removed from the antenna, making it easier to adjust the rejection band. The suggested antenna covers a UWB ranging from 3.1 to 10.6 GHz. Through a simulation, we found that the rejection characteristics of the suggested antenna can be changed among WLAN (5.75 GHz), C-band (4 GHz), WiMAX (3.5 GHz), and X-band (7.8 GHz), and that the measurements in the WLAN and WiMAX bands show rejection characteristics. Additionally, the suggested antenna has a peak gain of over 3 dBi in the operation band and shows omnidirectional radiation patterns. © 2016 Wiley Periodicals, Inc.
