Novel Method

<span lang="EN-US">This paper reports a novel method for designing a miniaturized microstrip antenna with DGS based on CSRR array which operates in the frequency of 2.6GHz for low band WiMAX application. The proposed antenna is designed using ANSYS HFSS simulation software. The antenna with optimized parameters is fabricated using FR-4 substrate of thickness 1.6 mm. The simulated and measured performances of the antenna in terms of return loss, directivity and radiation patterns are presented in this work. When Complimentary Split Ring Resonators (CSRRs) array are placed on the ground plane, the resonant frequency is shifted  to a lower value and patch size is reduced .The measurements were taken and compared with the simulated results. The performance characteristics obtained from the measurements show that the proposed antenna is suited for WiMAX application at 2.6GHz.</span>

Microstrip Patch

A compact triband microstrip patch MIMO antenna is proposed for WLAN applications. The antenna consists of two patches antenna elements, which are orthogonally placed to each other for high isolation at 2.4, 2.8 and 5.8 GHz frequency bands. On its ground plane, a Complementary Split Ring Resonators (CSRRs) is etched for size reduction and multiband generation. The proposed compact MIMO antenna covers an entire size of 58 x 45 x 1.6 mm3, with the patch size of 13.3 x 17.1 mm2. A 79% size reduction at 2.45 GHz was achieved for miniaturization, with a very low mutual coupling (S21 and S12) of -32 dB at all bands.

This paper presents the study of the ground plane effect in passband filters using metamaterial cells in Open Split Ring Resonators (OSRR) structures on microstrip substrates. Three different configurations have been proposed, namely: by removing partially the ground plane of the OSRR cell back end, by windows design over the ground plane at the back end of each cell and by placing a full ground plane. The conducted analysis shows that the filter transmission response featuring a ground plane including windows proved to be the most flattened with the middle bandwidth of the three configurations. On the other hand, the performance of these filters is similar to a conventional filter based on three-pole microstrip technology but with a considerable reduction in size of about 60%.

Compact Dimension

A band-removal property employing microwave frequencies using complementary split ring resonators (CSRRs) is applied to design a compact UWB antenna wishing for the rejection of some frequency band, which is meanwhile exercised by the existing wireless applications. The reported antenna comprises optimization of a circular radiating patch, in which slotted complementary SRRs are implanted. It is printed on low dielectric FR4 substrate material fed by a partial ground plane and a microstrip line. Validated results exhibit that the reported antenna shows a wide bandwidth covering from 3.45 to more than 12 GHz, with a compact dimension of 22 × 26 mm2, and VSWR < 2, observing band elimination of 5.5 GHz WLAN band.

Yagi Antenna

A traditional yagi antenna is used for broadband applications. A New Metamaterial Printed Microstrip Yagi -Array Antenna has been introduced here. This antenna is found to operate at 2.4GHz. The microstrip yagi-array antenna is loaded with artificial split ring resonators (SRRs) which is used for achieving the metamaterial effect in the structure. The overall circuit size of the designed antenna is 11.5*11.5*0.25mm3 with reduced cross polarization and the substrate used is FR4 epoxy with dielectric constant 4.4 which is readily available. The designed antenna achieved about 4dB of gain and it also achieved a high directional characteristic of 5-9dB in the operating band. The designed antenna had a minimum return loss of about -8dB. The achievement of narrowband width for ISM band application enhances the efficiency of the antenna at the specified band and reduces the interference level.

Scattering Wave

The split ring resonators (SRR) is designed to work at X band and its equivalent medium parameters are estimated by using the equivalent analysis method. The high gain microstrip antenna, which is based on Photonic BandGap (PBG) structure, is also studied. To make the scattering wave deviates mirror direction and reduce the out-band Radar Cross Section (RCS) without affecting the performance of antenna, the designed SRR is used as the cover of PBG structure microstrip antenna. The results show that the forward gain of PBG structure antenna is 0.8 dB higher than the tradition antenna. After the SRR covers on the PBG structure antenna, the gain of antenna is unchanged and the RCS of the mirror direction decreases for all incident angles, and the most decrement is 21.05 dB.
