A CPW-fed hexagon-shaped split ring resonator (H-SRR) antenna consisting of three concentric SRR rings is proposed for triband WLAN/WiMAX and Wi-Fi6 applications. A single port optimized antenna has a size of 43 × 22 × 1.6 mm 3 with two ports, and a multiple-in-multiple-out (MIMO) antenna based on the same H-SRR design is of size 95 × 52 × 1.6 mm 3 . The use of metallic loadings between the rings led to an impedance bandwidth of 21%/65% for the single-port H-SRR antenna and 33%/66.5% for the dual-port H-SRR antenna in the 2.4 GHz band and 5.2/6 GHz bands. The antennas exhibit a gain in the range of 2-2.7 dB and good radiation characteristics. Also, the proposed antenna design achieves the isolation of more than 30 dB without using any de-coupling network making the structure simple and compact. For tri-band applications of the proposed dual port antenna, the MIMO parameters ECC, TARC, DG, and MEG are found about < 0.005, < −10 dB, ≤ 10 dB, and < −6 dB, respectively in the 2.4/5.2/6 GHz bands without any decoupling structure. Measurements with a commercial transmitter at 5.8 GHz confirmed that these antennas offer better Wi-Fi 6 connectivity. Thus, the results confirm that the novel features of the proposed antennas are simple structure, wideband operation, and moderate gain with a compact size in the 2.4/5.2/6 GHz bands, and therefore, these presented antennas are useful in the current WLAN/WiMAX systems as well as upcoming Wi-Fi 6 applications like routers.

“…Although limitations like narrow bandwidth, impedance mismatch, and poor gain are quoted on conventional patch antennas, there are various advancements made on different sections of patch antennas to overcome their constraints. The implementation of fractal structures in the conventional patch antennas will miniaturize the size of the antenna and allow the antenna to operate from lower to higher frequency [2][3][4]; employing Flame Retardant 4 (FR4) as its dielectric medium for better reliability and mechanical strength [5]; implementation of Split ring resonators to the antenna design will engage LC tuning circuit which enhance the radiation effects of the antenna [6]; incorporating CPW feed and ground may enhance the bandwidth ratio and impedance bandwidth of the antenna [7].…”

A Koch Snowflake fractal structure embedded octagonal patch antenna with a hexagonal split ring for Ultra-Wideband (UWB) and 5G applications is proposed. In this proposed design, Koch Snowflake pattern is chosen for embedding into the octagon-shaped patch antenna, which tentatively develops a miniaturized cross-sectional area in the radiator and introduces wide resonance with enhanced gain. The complete dimensions of the proposed model are 25 × 30 × 1.6 mm 3 . The simulated design and fabricated prototype feature a Peak Gain of 6.3 dBi and 6.27 dB respectively; Fractional Bandwidth (FBW) of 168% (Frequency ranges from 2.6 GHz to 28.9 GHz) and 168% (Frequency ranges from 2.4 GHz to 28.5 GHz) respectively which are tested and measured using Microwave analyzer and anechoic chamber. Thus, the proposed antenna covers the resonance which includes S-band, C-band, X-band, Ku-band, and K-band. Also, it completely wraps the UWB spectrum range (3.1 GHz to 10.6 GHz), 5G (Sub-6 GHz band) Frequency Range 1 (FR 1) spectrum, and most deployed 5G mm-wave Frequency Range 2 (FR 2) spectrum (24.25 GHz to 29.5 GHz).

In this article, a tri-band Omega Complementary Split Ring Resonator (OCSRR) and Circular Complementary Split Ring Resonator (CCSRR ) loaded patch antenna is presented for Wi-Fi 6E/7 applications. The proposed antenna consists of a rectangular patch, circular and omega shaped CSRR which is designed at 6GHz,5GHz and 2.4GHz respectively. The parametric studies have investigated to optimize the antenna parameters in desired frequency bands using Ansys HFSS 21.0 software. The measured and simulated results are in good in agreement. In addition, the operating principle, equivalent circuit, and negative ɛ parameter of the OCSRR and CCSRR metamaterial structures are also investigated. Compared to the conventional antenna, the proposed antenna has a compact size of 0.21λg × 0.28λg × 0.02λg (where λg is the guided wavelength in free space at 2.4 GHz) and size reduction of 81.9%.
