High directivity microstrip antenna with stopband and passband frequency selective surfaces for 6G at low-THz

Abstract

There is still no high-directivity microstrip antenna with directivity beyond 25 dBi, bandwidth (BW) of more than 24%, which can be used for 6G cellular communication at low-THz at a resonance frequency of 144 GHz. So, duo broadband microstrip antennas have been designed at a resonance frequency of 144 GHz with the Taconic TLY-5 laminate in this work. These designs were carried out with the computer simulation technology microwave studio (CST MWS) software. The first antenna simulation results were compared within an Ansys high-frequency structure simulator (HFSS) software, and the obtained simulation results from both software were in fair consent, supporting the proposed designs. The peak directivity, peak gain, total peak efficiency, and BW obtained for the proposed THz microstrip antennas were 27.01 dBi, 25.3 dB, 78.96%, and 34.21 GHz (24.93%), respectively. Therefore, these antennas can be a base for 6G at low-THz.

6G Broadband and High Directive Microstrip Antenna with SIW and FSSs

“…The first design was simulated with the Ansys HFSS to compare the simulation results of this designed antenna simulated within the CST MWS, and the simulation results attained from the couple simulators were in fair compromise. It may have been displayed that these paperwork simulation results were validated within simulator validation and similar to that in [24], [41]- [43]. The simulation was done with the CST MWS, and validation was done with the Ansys HFSS, like work [24].…”

“…An effective way to verify the results of antenna simulations is by validating and measuring with a manufactured prototype antenna. However, it is possible to do a simulation with two simulation software that works with different techniques, as is done in the articles [41]- [43], to get an approximate and cheaper estimate of the accuracy of the simulation results. We chose software validation/comparison in this paper as described above.…”
