| Popis: | The proposed metamaterial-based MIMO antenna has four individual elements, each of which is fed by a microstrip feed. The total width and length of the structure are respectively 60 and 52 millimetres. The metamaterial is dispersed from the fields with the strongest coupling by being printed on a patch. This makes the isolation better. The distributions of the fields are altered as a result of the electromagnetic fields' interactions with the metamaterial structure, which reduces the number of coupled fields. The suggested antenna design is the simplest and takes up the least amount of area because metamaterials are produced as patches. The proposed architecture's strong impedance bandwidth operates at 18.3 GHz, 10.8 GHz, 12.3GHz, 13.7 GHz, 16.1 GHz, 18.1 GHz. The suggested structure has all four ports of excitation, a gain of greater than 6.dBi on all operating bands, and a broadside radiation pattern. Tolerable levels of error (ECC and CCL) are achieved in their respective operational bands. A prototype of the proposed antenna is then constructed and evaluated. Because the simulated value and the measured value are so close to one another, MIMO is the most efficient form of wireless transmission. |
