“…Structural monitoring is another sector of relevant impact due to the sensitivity of SRRs to small displacements [ 8 , 42 , 43 ]. In the telecommunications field, the use of SRRs regards wireless power transfer (WPT) [ 44 ] and modulation of the signal transmission band [ 45 ] (i.e., for WLANs [ 46 ] and wearable devices [ 47 ]), through either the definition of filters or the development of broadband and multiband devices [ 48 , 49 ]. Clearly, a dynamic tuning of the SRR response and its resonance frequency would be highly desirable for enabling novel opportunities for telecommunications, such as enhancement of isolation in higher frequency bands and access to multiband satellite and radar communications.…”

A novel approach for dynamic microwave modulation is proposed in the form of reconfigurable resonant circuits. This result is obtained through the monolithic integration of double split ring resonators (DSRRs) with microelectromechanical actuators (MEMS) for geometrical tuning. Two configurations were analyzed to achieve a controlled deformation of the DSRRs’ metamaterial geometry by mutual rotation or extrusion along the azimuthal direction of the two constituent rings. Then, the transfer function was numerically simulated for a reconfigurable MEMS–DSRR hybrid architecture where the DSRR is embedded onto a realistic piezo actuator chip. In this case, a 370 MHz resonance frequency shift was obtained under of a 170 µm extrusion driven by a DC voltage. These characteristics in combination with a high Q factor and dimensions compatible with standard CMOS manufacturing techniques provide a step forward for the production of devices with applications in multiband telecommunications and wireless power transfer and in the IoT field.

“…A number of researchers have reported microstrip patch antennas for IoT applications such as a microstrip line fed truncated icosidodecahedron modeled antenna [7]. Also, etching defected ground structures (DGS) of a simple shape in the ground plane, or a complicated shape for the better performance [8,9,10], and use of a metamaterial split ring resonator [11,12] have been reported in recent literatures. This paper describes a new design of microstrip patch antenna where a DGS was loaded on the ground plane to generate multiple resonance frequencies for different applications in IoT bands.…”

A new design of a multiband microstrip patch antenna using slots in the patch as well as defected ground structures (DGS) implemented in the ground plane is proposed. Multi resonance response was obtained by etching the DGS shapes in the ground plane of a Traditional patch operates at 5.2 GHz, which is the common frequency for the Internet of Things (IoT) applications. The novel outcome of this work is a compact antenna that resonates at three bands, viz. 2.42, 5.22 and 5.92 GHz. Different shapes of slots were used to improve the antenna performance at the different resonances. The antenna used the inset feeding technique to improve impedance matching. Rogers RO3003 substrate of 3 relative dielectric constant, 0.0013 loss tangent, and 1.5 mm thickness was used to build the antenna. The designed antenna was simulated using HFSS software. The good consistency between simulations and measurements confirmed the antenna's ability to improve the benefits for IoT applications at the three different frequencies.

“…The metamaterial split ring resonator was incorporated into the patch antenna in [23], and the resulting design achieved a resonant frequency between 4.8 GHz and 5.2 GHz. Metamaterial slip ring resonator is also used in [24], the metamaterial resonator produced 22.2% reduction in the size of the antenna, concluding that miniaturisation can be achieved by using a metamaterial slip ring resonator.…”

This paper introduces the design of a high-gain wideband microstrip patch antenna for sub-6 GHz 5G communication. The proposed antenna integrates a novel defected ground structure (DGS) for achieving the wide bandwidth. The ground plane uses a triangular strip inserted into the ground plane to improve the performance of the antenna. It also uses the reflective plate to concentrate the side lobes and minimise the production of the back lobe, thereby boosting the main lobe of the radiated signal and thus increasing the gain of the proposed antenna. The proposed antenna uses the FR-4 epoxy substrate with an inset feed technique in its design. The simulation and optimisation of the proposed antenna were carried out with CST Microwave Studio Suite. The antenna design is compact with a dimension of 28:03 23:455:35mm3 and a maximum gain and directivity of 6.21 dB and 7.56 dB respectively, with a radiation efficiency of about 80%. The proposed antenna operates from 4.921 GHz to 5.784 GHz, which covers the 4.9 GHz-5.8 GHz of the sub-6 GHz 5G communications spectrum. Fabricated and measured result of the antenna confirm simulated results.
