This paper compares the characteristics in the time-domain of Ultra-wide Bandwidth (UWB) monopole antenna and wide slot antenna. Whether the UWB antenna is suitable for the signal transmitting is not only measured by antenna’s width but also by the characteristics of the time domain. These two antennas are proved to be fit for sending and receiving signals in frequency domain. In this paper, th...

In this article, a novel dual-band microstrip monopole antenna based on split-ring elements is proposed for WLAN (2.4/5 GHz) applications. The antenna fed by a two-stage microstrip line has fairly small dimensions and provides 7.5 and 25.5% impedance bandwidth performance at the respective bands. Also, the antenna exhibits almost uniform radiation patterns at each frequency band. The measuremen...

This paper describes the comparision of a microstrip-fed monopole ultra wideband antenna with and without notch. In case of notch the notch-band characteristics is achieved by Cshaped ring resonator. The paper gives better understanding of antenna parameters such as return loss, VSWR etc., and its variation in performance of antennawith and without notch. Also presents the effect of parameters ...
