“…The Koch fractal microstrip patches are commonly used in virtue of their attractive properties: they have small size, a single feeding port is enough and their higher order modes result in directive radiation patterns [58]- [60]. The basic geometry of the Koch island is obtained by replacing the sides of an equilateral triangle by a Koch curve.…”

Abstract-A coupled defected ground structure (CDGS) is presented which is synthesized by etching Von Koch fractal shape slot in the ground plane and series capacitive gap in the conductor strip. Unlike the structures loaded with complementary split ring resonators (CSRRs), the proposed structure can operate at very wide band. A UWB filter using the above structure is fabricated and tested. The relative bandwidth of the −10 dB return loss is 128% and the insertion loss is better than 1.5 dB except at high frequencies. The equivalent circuit model of the proposed structure is presented and the electrical parameters are also extracted. The circuit model results are compared with the simulated and measured results which verify that the equivalent circuit model is reasonable.

“…So many researches have been done on antenna miniaturization and various methods have been used for designing small antennas such as loaded antennas with lumped elements. The application of high dielectric constant materials [5], the application of slotted ground and short circuit [6], the optimal antenna geometry [7], the fractal antenna [8], and using of the composite right/left-handed (CRLH)-TL technique [9] are noticed for miniaturization. Electromagnetic band gap (EBG) structures are well-known metamaterial with a periodic structure that consists of metal or dielectric elements, which are showing the band pass or band stop characteristics [10].…”

In this paper, combination of electromagnetic band gap (EBG) and split-ring resonator (SRR) loads with fractal formation for miniaturization of microstrip antenna is noticed. Here two different shapes of antenna have been studied with two wellknown metamaterial structures as parasitic elements. A conventional microstrip antenna, which is surrounded by four EBG unit cells, is chosen as the first antenna. It has an effective resonance at 2.5. The Minkowski fractal method is applied to EBG unit cells in this stage. The Minkowski fractal structure is implemented for accession of effective capacitance in EBG unit cells. The second antenna frequencies are 2.5 and 5.9 GHz. It contains a slot structure with four SRRs, used for making parasitic elements and for achieving multi-band characteristic. The fractal method is used to improve the inductance of SRR structure by increasing the effective length of microstrip line. At this stage, the applied fractal structure has been modified, so that the frequency of wireless application could be achieved. In the last step, by some changes in feed line of the slot antenna, circular polarization (CP) is obtained for the second antenna, which shows that SRR load can be helpful for making the CP.
