The manuscript represents a novel superstrate metamaterial loaded microstrip patch antenna to achieve multiband frequency reconfigurability. The performance is observed for the frequency band of 4 to 8 GHz. Metamaterial property is enabled by engraving triangular-shaped split-ring resonators in the substrate. Frequency tunability is achieved based on the switching mechanism of three PIN diodes. Different materials are loaded in the split ring resonators like copper, distilled water, and seawater for the performance observation in terms of reflectance response, Bandwidth, gain and tunability. The design provides the reflectance response of À43.38 dB, Bandwidth of 220 MHz, and frequency tunability of 100 MHz. The proposed design is also giving the highest gain of 8.3 dB. The structure is fabricated using FR-4 to reduce the overall cost of the antenna, and it is tested using a vector network analyzer and anechoic chamber. Simulated results and fabricated ones are compared for reliability. The proposed design, with its flexible and reconfigurable capability, can be applicable in IoT applications.

The presented article represents the rudimentary-shaped effective 1 × 2 MIMO antenna structure. The five variation types in the ground region shape are analyzed. The structure's total dimensions are 40 × 36 × 1.6 mm 3 . For efficiently manufacturing, the low-profile substrate FR4 is employed, and the reflectance response of a simulated and modelled design is compared. The placement of two T-shaped slits in the ground area aids in achieving a wider bandwidth, multiband response, excellent Gain, and directivity. Overall, the PW:4 has a minimum reflectance coefficient of −34.54 dB, a broad bandwidth of 3.38 GHz, a peak gain of 13.02 dB, maximum narrow band isolation of 62 dB, and a maximum normalized directivity of 156°. The Envelop Correlation Coefficient, Channel Capacity Loss, Total Active Reflection Coefficient, and Diversity Gain for MIMO design are also examined. These findings indicate the provided design's behavior as per the standard requirements.

We proposed a novel approach based on a complementary split-ring resonator metamaterial in a two-port MIMO antenna, giving high gain, multiband results with miniature size. We have also analyzed a circular disk metasurface design. The designs are also defected using ground structure by reducing the width of the ground plane to 8 mm and etching all other parts of the ground plane. The electric length of the proposed design is 0.5λ × 0.35λ × 0.02λ. The design results are also investigated for a different variation of complementary split-ring resonator ring sizes. The inner and outer ring diameters are varied to find the optimized solution for enhanced output performance parameters. Good isolation is also achieved for both bands. The gain and directivity results are also presented. The results are compared for isolation, gain, structure size, and the number of ports. The compact, multiband, high gain and high isolation design can apply to WiMAX, WLAN, and satellite communication applications.
