“…Defected ground structure not only provides the impedance bandwidth but also explores the multiband resonance. Usage of Slot [8][9][10], defected ground structures [11], fractal shapes [12], active and passive devices [13,14] are widely used in the realization of multiband operating. Although various techniques are used for multiband realization, the major disadvantage of this method is a complex design, increased size, and reduced gain.…”

A rectangular monopole engraved with an open complementary split-ring resonator (OCSRR) metamaterial is designed and proposed for multiband radio applications. The proposed antenna has a rectangular monopole feed with offset microstrip feed, and the OCSRR designed at 3.14 GHz is engraved in the radiating element. The OCSRR is a special type of metamaterial with small electrical size. The OCSRR modifies the current direction due to its negative permittivity, which creates another resonance at 3.16 GHz. The left offset feed and abridged ground length creates another resonance at 3.82 GHz and responsible for good impedance matching are achieved in all the resonating bands. The entire antenna is designed and fabricated on the FR4 substrate with a complete measurement equal to 27.84 mm x 23.25 mm x 1.6 mm. The proposed structure shows the multiband characteristics at 3.16 GHz, 3.82 GHz, and 5.14 GHz with a S 11 of -19.83 dB, -17.90 dB, and -55.73 dB, respectively. The critical parameters of the OCSRR are decided using the parametric analysis, and the simulated results are presented. The OCSRR negative permittivity extraction is done with NRW wave guide extraction method, and the result is validated with the help of OCSRR resonant frequency calculation. The uniformity is well maintained between the measured and simulated results. The multiband characteristics, reasonable gain, compactness, low design complexity, and small size are the significant features of the proposed antenna

The effect of metamaterials, whose positions are determined with particle swarm optimization (PSO) algorithm on the performance of the defected ground structure antenna is investigated. For this purpose, four different optimization studies are carried out. In Case I, the positions of the flower shape metamaterial (FSMM) structures on the antenna are determined classically at equal intervals and added to the antenna to obtain highest gain, and it is revealed that the gain is increased by 26%. In Case II, the positions and rotation angles of the FSMMs on the antenna are determined and the gain increase by 36%. In Case III, FSMMs are placed on a layer at equal intervals with the classical method. In this case, 56% increase of antenna gain is achieved. In Case IV, the positions and rotation angles of the FSMMs is formed on the lens independently of each other with PSO. In this last case, with dimensions of 24 Â 36 mm 2 , a 77% increase in antenna gain is achieved compared to the reference antenna at the resonant frequency of 12.65 GHz in dBi. As a result, it is observed that the use of metamaterials with the help of the PSO algorithm has a higher effect on antenna performance than the use of MMs with the classical method.
