Investigation and measurement of square strip line antenna design and characteristic mode analysis for 5G/WiFi/WLAN applications

Abstract In this paper, two novel compact low-profile dual-band plasmonic antennas designed with the help of Characteristic Mode Analysis and parametric study are presented. The plasmonic antennas contain microstrip line-fed strip-loaded patches and partial ground planes. The final proposed antennas cover the two bands in the frequency range of 2.4-2.5 GHz and 5-6 GHz. Plasmonic antennas offer nearly omnidirectional patterns at the desired frequency ranges. Additionally, a detailed parametric study of almost all the design parameters is performed to display the effect of varying those parameters on the resonance frequency at both bands. The parametric study for both antennas has been carried out to optimize the antenna and get better-enhanced results. The antenna is also fabricated and measured results are obtained. The comparison of results shows a good similarity between the simulated and measured results. The designed antenna can be applicable for 5G/ WiFi/WLAN applications.
