The massive mobile data requirement has increased, in last ten years, mainly due to the video content. This is due to the capability of mobile handsets supporting 4k resolution which requires the data rate of 15.4Mbps[1]. This increase is due to the increasing number of user and viewing time. This will result in an annual traffic of 296.8 excabytes(EB) by 2019[2]. Therefore, 5G communication network (IMT 2020) is the suggested solution to match this high data demand, with a capability of reaching up to data rate of 20Gbps. 5G is not only targeting enhanced mobile broadband (eMBB), but also it has diverse usage scenarios including, ultra reliable and low latency communication (URLLC) and massive machine type communication(mMTC). In order to meet with the design challenges of 5G , frontend antenna layout for base stations and mobile hand set is an intense area of research. Recently, technology of ultra-wideband has received high importance and growth in wireless communication systems due to its remarkable features. Federal Communication Commission (FCC) has allocated a frequency band ranging from 3.1 GHz to 10.6 GHz for such applications [3-8]. These systems are characterized by extreme high data rates over their wide bandwidth, low power consumptions [9-12]. Hence, designing a compact antenna with high performance in terms of operating frequency, radiation pattern, power gain, and fabrication cost remains a challenging task[13-17]. Micro strip patch antennas are widely used in ultrawideband systems due to their advantages such as low cost, simplicity, light weight, and structure size. Thus, proposed antenna is a patch semi-circular antenna fed by a micro strip line as shown in figure 1(a). Next section will present details of the antenna structure and parameters. Antenna Design Fig.1 shows the geometry structure of the proposed semi-circular monopole antenna. The entire design and parametric optimization process have been[...]
