“…Step 4 CSRR characteristics have been widely exploited by antenna designers to achieve various desired parameters. It has seen to be used in literature to achieve lower resonant frequencies in miniaturized antenna [26], to realize bandpass and bandstop filters [22,27], to enhance isolation in MIMO antenna systems, [28], and so on. The circuit models corresponding to CSRR are not very accurate because circuit modal of unit cell must take into account the coupling between the resonator and the line, i.e., interresonator coupling.…”

A compact, dual-port, triband MIMO antenna is designed and tested for three sub-6 GHz WLAN bands for IoT applications. The size and performance of the antenna make it versatile for the emerging IoT applications communicating using the 2.4 GHz, 5.2 GHz, and 5.8 GHz WLAN frequencies. The single radiating element of antenna geometry includes a pair of modified and optimized rectangular patches. A complimentary split ring resonator (CSRR) structure is incorporated in the ground plane as a defect (defected ground structure) to attain the third operational band. The orientation of the elements, orthogonally arranged, along with DGS, enhances the isolation between the radiating elements keeping it below 18 dB throughout the three operating frequency bands. The size of the final antenna is as small as 0.32 λ 0 × 0.32 λ 0 mm2 build on commercially available and cheap FR4 substrate of thickness 1.5748 mm. A peak gain of 7.17 dBi is attained for the proposed MIMO system. This MIMO antenna also satisfies the diversity parameter requirements including DG > 9.8 , ECC < 0.5 , TARC < − 10 dB, and CCL < 0.5 bits/s/Hz. This makes the proposed antenna a good candidate for IoT applications employing WLAN frequencies.

“…To reduce this mutual coupling, various mutual coupling (MC) reduction or decoupling, or isolation enhancement techniques were introduced in the literature. They are neutralization line (NL) [2], decoupling network (DN) [3][4][5][6], metasurface, metamaterial (MTM) [7], electronic band gap (EBG) [8,9], frequency selective surface (FSS), photonic band gap (PBG), optically transparent structures [10], split ring resonator (SRR), complementary split ring resonator (CSRR) [11,12], dielectric resonator antenna (DRA), ground plane modification (GPM), defected ground structure (DGS) [13,14], slots [15][16][17][18], band notching techniques implementation, parasitic elements, metal strips, shorting pins, insertion of stubs [19][20][21], frequency reconfigurable [22,23], implementing PIN diodes, microstrip open loop resonator (MOLR), quasi self complementary antenna (QSCA) [24], inter element spacing [25][26][27][28][29], insertion of slits, fractal structures, modified substrates, locating antennas on different substrate layers, etc. These techniques improve impedance matching, enhance gain, efficiency, and increase the complexity of antenna design.…”

This present article reports a high isolation four-port Wrench shaped compact UWB MIMO antenna with a novel decoupling network in the ground plane, and its step-by-step evolution is presented for 3.1-10.6 GHz. The proposed four-port MIMO antenna is fabricated on an FR4 substrate of size 44 × 44 mm 2 (0.342λ 0 × 0.342λ 0 ), where λ 0 is a free space wavelength at 2.33 GHz, with 7 mm edgeto-edge spacing between the radiating elements. It consists of four orthogonal symmetrically placed identical radiating elements each of which has a Wrench-shaped circular patch with a rectangular slot cut in the partial ground. The performance characteristics of this MIMO antenna are reflection coefficients S 11 ≤ −10 dB in the range from 2.33 GHz to 11.7 GHz, mutual coupling coefficients S 21 ≤ −28.24 dB, and S 31 ≤ −22.35 dB. The maximum peak gain is 5.15 dBi at 9.2 GHz, and minimum is 1.27 dBi at 3.1 GHz. The maximum efficiency is 98% at 4.66 GHz, and the minimum is 93% at 6 GHz. The diversity parameters of proposed four-port MIMO antenna are reported as ECC ≤ 0.2, DG ≤ 10, TARC ≤ −10 dB, the ratio of MEG between any two elements is near unity, and CCL < 0.38 bits/s/Hz in the band of interest. The design is fabricated and measured. The measured and simulated results are in good agreement and are within the permissible limits.
