Abstract

To support various fifth generation (5G) wireless applications, a small, printed bowtie-shaped microstrip antenna with meandered arms is reported in this article. Because it spans the broad legal range, the developed antenna can serve or reject a variety of applications such as wireless fidelity (Wi-Fi), sub-6 GHz, ultra-wideband (UWB) 5G communications due to its multiband characterization and optimized rejection bands. The antenna is built on an FR-4 substrate and powered via a 50-Ω microstrip feed line linked to the right bowtie’s side. The bowtie’s left side is coupled via a shorting pin to a partial ground at the antenna back side. A gradually increasing meandering microstrip line connected to both sides of the bowtie to enhance the rejection and operating bands. The designed antenna has seven operating frequency bands of (2.43 – 3.03) GHz, (3.71 – 4.23) GHz, (4.76 – 5.38) GHz, (5.83 – 6.54) GHz, (6.85 – 7.44) GHz, (7.56 – 8.01) GHz and (9.27 – 13.88) GHz. The simulated scattering parameter 𝑆11 reveals six rejection bands with percentage bandwidth of 33.87%, 15.73%, 11.71, 7.63%, 6.99%, 12.22% respectively. The maximum gain of the proposed antenna is 4.46 dB. The suggested antenna has been built, and the simulation and measurement results are very similar. The reported antenna is expanded to a four-element design to investigate their MIMO characteristics.
