A Review of Ultra Wideband Antennas with Band Notched Characteristics

Abstract

The rapid growth has been observed over the last decades in the field of Ultra-wideband technologies. Due to the large bandwidth and less power consumption UWB system provides an eccentric solution for wireless communication of short range in both reception and transmission. The printed monopole antenna has been preferred for implementing UWB technology due to its distinct features such as ease of fabrication, light weight, low cost, compatibility with other systems etc. Basic requirement for designing these antennas is to avoid the interference by applying the notch band characteristic using different techniques. These techniques are continuously upgraded to improve the performance of the antenna designed under UWB technology with band notch characteristics. In this manuscript, an extensive literature review has been studied and presented on UWB antenna with band rejection characteristics proposed by distinct researchers in the last decade. In the reviewed literature, the existing UWB antennas has been characterized according to notch bands and classified into various categories such as single, dual and triple band notch characteristics. Further, the different techniques applied by the researchers are also explained in detail in the sub-sections. Moreover, the design of different types of UWB antennas has also been discussed in this paper, which may be helpful for the future research work.
