“…In contrary, the second group consists of the studies which promise lower gain values, however higher % ESR [27,30,32]. The third group consists of the studies which promise both lower gain and lower % ESR [18,45]. It is important to note that references [32] and [45] applied some major geometrical modifications on the metallic patch in addition to DGS structure.…”

In this study the effects of using defected ground structures (DGS) composed of a complementary split ring resonator (CSRR) and CSRR with dumbbell (CSRR-D) for rectangular microstrip antennas are investigated. On this aim, two different antennas, which are Antenna B having CSRR etched DGS and Antenna C having CSRR-D etched DGS are designed and fabricated in comparison with the ordinary rectangular patch antenna, which is Antenna A. In both Antennas B and C, CSRR structures are etched in the same position of the ground planes. On the other hand, another ordinary microstrip antenna, called Antenna D, is designed at resonance frequency of Antenna C. For the characterization; resonance frequencies, voltage standing wave ratios, percentage bandwidths, gains, ka values and gain radiation patterns are investigated both in simulations and experiments. The numerical analyses show that 29.39% and 44.49% electrical size reduction (ESR) ratios are obtained for Antenna B and Antenna C, respectively in comparison to Antenna A. The experimental results verify the ESR ratios with 29.15% and 44.94%. Supporting, Antenna C promises 68.12% physical size reduction (PSR) as it is compared with Antenna D. These results reveal that Antenna C is a good alternative for DGS based microstrip electrically small antennas.

“…Due to the negative value of permittivity, the CSRR structures help in designing antennas with integrated filters. An antenna with a CSRR structure to suppress two possible image frequencies in a superheterodyne receiver was proposed in [14]. A GA based optimization technique is validated by designing an antenna with CSRR at its ground plane.…”

“…CSRR structure is reported in the use of dual-band [9][10][11] and UWB antennas with integrated filter [12], [13]. The CSRR structure is also reported in an antenna for a superheterodyne receiver which has an inherent capability to eliminate two possible image frequencies [14].…”

“…In this paper, a GA-based approach is used to optimize the dimensions of a CSRR structure for the designing of a microstrip antenna with an integrated filter. The CSRR structure has two resonant frequencies where it acts as a notch filtering element owing to the negative value of its effective permittivity (ε r ) [14]. The two resonant frequencies depend upon the dimensions of the CSRR structure.…”

Soft-computational approaches have enabled quicker and more efficient means for antenna design. In the present work, a genetic algorithm (GA) based method is reported for the design of complementary split-ring resonator (CSRR) structures for antenna design. A multi-objective optimization problem is formulated to design the antenna. The cost function of the optimization problem is calculated from a surrogate model of the CSRR structure. The surrogate model is created first using an analytical model of the CSRR structure and then using an artificial neural network (ANN). A comparative study of the result shows that the ANN-based surrogate model is accurate as compared to the surrogate model using an analytical approach. An antenna with an integrated filter is fabricated using a CSRR structure designed applying the proposed method. The performance of the antenna is validated from the simulation and measurement results.

A miniaturized multiband printed monopole antenna is reported using hexagonal complementary split ring resonator (HCSRR) slots. Antenna miniaturization and multiband are accomplished by employing metamaterial inspired structure HCSRR. The proposed antenna consists of three HCSRR slots, it makes the antenna to resonate at 1.62 GHz, 2.4 GHz, 3.3 GHz, and 5.8 GHz frequency bands. The designed antenna structure has a small size of 20 × 20 × 1.6 mm3, which is fabricated on an FR‐4 substrate with dielectric constant |ɛnormalr of 4.4. The pass band characteristics of HCSRR are examined in detail for acquiring multiband abilities of the compact antenna, which is evaluated by use of the precise LC equivalent circuit design equations. The metamaterial property of the HCSRR is also studied to validate the resonance frequencies of the proposed antenna. Simulated and tested data are investigated. The prototype antenna has adequate advantages, with a simple structure, compact size, multiband, and uniform radiation patterns.
