Abstract
The goal of this work was to design, simulate, build, and test bow-tie antenna for 5G networks. In this paper, it will be shown how the radiation pattern and input match are improving by changing angles on some points of the antenna. The first angle is from the central point of the bow-tie antenna (mark A) and another angle is from the side points of the bow-tie antenna (mark B). Bandwidth improvement is shown in the simulation between 4 GHz and 6GHz. S11, E?, E? for the nominal design are -27.31 dB, 7.39 dB, -3.30 dB respectively. After simulations, the nominal antenna is fabricated and tested with reference antenna A-info LB8180. Simulation results, testing results with fabricated antenna, and angle change results will be shown in further text.
Highlights
When the first commercial cellular network has launched in 1979 by “Nippon Telegraph and Telephone” it was clear that world is entering in whole new era with wireless technologies, but the true wireless revolution started at 1990s [1]

Summary
When the first commercial cellular network has launched in 1979 by “Nippon Telegraph and Telephone” it was clear that world is entering in whole new era with wireless technologies, but the true wireless revolution started at 1990s [1]. In the table below [4] it can be observed that in range of 50 years network bandwidth is improved around 1,000,000 times, which shows that world is getting more and more connected through different devices and that needs a huge amount of network bandwidth. Making circular arc sides for the bow-tie antenna have a significant role to improve the parameters which will be shown through the paragraphs in this paper. For this bow-tie antenna S11 is -27.31 which is really good if we consider dimensions.
