A Frequency Tunable Hexagon Shaped Antenna for 5.8GHz-WiFi and Sub 6 - 5G Mobile IoT Applications

In this paper, a monopole UWB broadband antenna is designed, fabricated, and measured for wireless communication networks. The initial radiator model of the proposed antenna has a short-sleeve shape, and to expand the impedance bandwidth, the right and left angles are subtracted symmetrically from the lower half of the radiator. The impedance matching is improved by etching slots in the feed line and adding L-shaped patches symmetrically on both sides of the feed line. The results show that the proposed miniaturized antenna system can cover WiFi 7(2.4–2.484 GHz, 5.15–5.35 GHz, 5.725–5.825 GHz, 5.925–7.125 GHz), 4G LTE (2.3–2.39 GHz, 2.555–2.655 GHz), 5G (4.8–5.0 GHz), X-band (7–12.4 GHz), Ku-band (10.7–14.59 GHz), and C-band uplink bands (5.925–6.425 GHz). Moreover, the antenna is found to be omnidirectional at low frequencies, with a maximum peak gain of 5.43 dBi. The antenna can be used for multi-frequency wireless communication applications.

“…In [19], a Wi-Fi/WiMAX/5G textile antenna is designed and resonates at multiple frequencies in 2.4-37 GHz with narrow bandwidths (BWs) and cluttered patterns at high frequencies, inapplicable for practical communication applications. In [20], a frequency tunable 5G/ Wi-Fi antenna is proposed, which achieves tuning by connecting PIN diodes to different metamaterial units. But the antenna still has only one channel and polarization.…”

“…In [23], an ultra-wideband antenna with circular polarization is designed for 5G/WiFi-5/WiFi-6 multi-functions, but similar to [19], the antenna pattern becomes cluttered at high frequencies. All designs in [20][21][22][23] have not been fabricated and experimentally verified, and the results are only from simulations. In [24], a flexible transparent antenna for 5G N78/N79 band and 5 GHz Wi-Fi band is designed and fabricated.…”

In this paper, a frequency selective surface (FSS) based shared-aperture antenna is designed for 5G/Wi-Fi applications. The 5G and Wi-Fi channel are separated to achieve different polarizations and simultaneous work. The proposed antenna is of ±45°-polarization in the 5G N79 band and vertical polarization in the Wi-Fi5.8 GHz band. The antenna is vertically stacked with the N79 band antenna located above the Wi-Fi band antenna. The N79 antenna is composed of FSS units with transmissive characteristics in the Wi-Fi band, and serves as an electromagnetically transparent surface to avoid blocking the Wi-Fi antenna. A prototype of our design is fabricated, assembled and tested, and measured results show that the prototype is able to cover the entire N79 band (4.1–5.2 GHz, 23.7%) and Wi-Fi5.8 GHz band (5.73–5.89 GHz, 2.8%). Measured average gain is 8.2 and 7.8 dBi in the N79 and Wi-Fi band, respectively, and radiation efficiency is over 86 and 80%. The proposed design exhibits separated channels, tri-polarizations, high gain and compact size, which is sufficient for regular 5G/Wi-Fi applications. The antenna also achieves a relatively wide and highly consistent signal coverage in the two bands, making it suitable for 5G/Wi-Fi multi-function communication and indoor 5G blind compensation.
