“…In this case, the LH frequency is 3.79 GHz by numerical modeling for gap capacitance and via inductance from (1) and (2) and by simulation of simple patch, we can assume RH frequency as 5.53 GHz. Therefore, the zeroth-order resonance (ZOR) is obtained 4.57 GHz and simulation is achieved at 4.59 GHz by (3).…”

“…IEEE 802.11a, IEEE 802.11bg, and Hyper LAN/2 standards are covered WLAN frequencies. The IEEE 802.11 standard has three frequency bands at 2.4 GHz (2.484–2.4), 5.2 GHz (5.35–5.15), and 5.8 GHz (5.825–5.725) and the frequency range in 3.3–3.8 GHz, which has been allocated for wireless personal area network (WPAN) and WiMAX [1–3]. New modern communication systems need microwave components with high performance and small size, so compact antennas are required.…”

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.

“…Among these applications, UWB antennas are very important devices for high speed rates, low cost, low power wireless systems and broadband usage [3,4]. The Federal Communications Commission (FCC) allowed application of the frequency band 3.1 to 10.6 GHz for UWB systems [5]. On the other hand, various applications of UWB communication systems exist in different frequency bands, such as 5.…”

Abstract-A novel fork monopole antenna is presented using metamaterial structures. The prototype monopole antenna consists of split-ring-resonators (SRR) as an electric-LC resonator and small ground. To prove the concept, the prototype antenna is designed and fabricated for wireless communication systems. The monopole structure makes ultra wideband (UWB) impedance bandwidth condition for 2-12 GHz. On the other hand, the prototype antenna shows dual notch band characteristics at 3.5-4.5 GHz and 5.3-6 GHz for WiMAX and WLAN rejection. The prototype antenna radiates omnidirectionally and has a gain altered between −4.5 and 6.2 dBi in 2.5-12 GHz, with an average gain of 4.2 dBi. The metamaterial model is suggested for the CRLH (ELC) resonator, and in addition, the parametric study for CRLH (ELC) resonator is presented for clarification of its manner on resonance controlling. Here, the final model antenna is fabricated on an FR-4, and experimental results are compared with simulations.
