Meandered multiband metamaterial square microstrip patch antenna design

Magnetic properties can be imparted to a naturally nonmagnetic material by metallic inclusions. A multiband meandered square microstrip patch antenna loaded with such a metamaterial is reported. Metamaterials exhibit qualitatively new electromagnetic response functions that cannot be found in nature. The inclusion of these structures allows simultaneous operation over several frequencies. The antenna was designed to function in multiple bands in the frequency range 0.6–2.2 GHz. The antenna has eight working frequency bands and its centre frequencies are 670 MHz, 1185 MHz, 1293 MHz, 1747 MHz, 1909 MHz, 1999 MHz, 2063 MHz and 2134 MHz. The metamaterial also enhances the gain of the antenna, which is applicable for several wireless applications. Design results were obtained by a high frequency structure simulator which is used for simulating microwave passive components.

Design of Microstrip Meandered Patch Antenna for Mobile Communication

The enhancing bandwidth and size reduction mechanism that improves the performance of a conventional micro strip patch antenna on a relatively thin substrate (about 0.006 λ ), is presented in this research. The design adopts meandered patch structure. Introducing the novel meandered square patch, offer a low profile, broadband, high gain, and compact antenna element. The proposed patch has a compact dimension of 0.384 λ × 0.384 λ (where λ is the guided wavelength of the centre operating frequency). The design is suitable for applications with respect to a given frequency of 750-1100 MHz. The simulated bandwidth of the proposed antenna is about 39%.

In this paper, for the very first time, four corners truncated triple band square patch antenna loaded with Split ring resonator (SRR) structure has been reported. Based on truncated square patch antenna, it has a double split square ring resonant structure embedded in the center of the substrate of the square patch antenna. The resonant structure has a strong electric response in a certain frequency of interest, and can be used to construct metamaterial. The antenna is designed to function in triple bands in the frequency range of 0.5-2.0 GHz.

Broadband compact microstrip patch antenna design loaded by multiple split ring resonator superstrate and substrate

Abstract We present microstrip patch antenna loaded with multiple split ring resonator substrate and superstrate. We analyze how the loading of split ring resonator superstrate and substrate can improve the bandwidth compared to the simple microstrip patch antenna and microstrip patch antenna loaded with split ring resonator superstrate. Another important observation is made for multiple split ring resonator loading in superstrate and substrate of microstrip patch antenna. The design is compared for two, three, and four-ring split ring resonator loading. The designs are also compared for different gap spacing between the rings. All three designs are compared for small gap and large gap between the rings. The design results in the form of reflection coefficient and bandwidth is presented in this manuscript. The design results are also compared with previously published designs.

Complementary split ring resonator metamaterial to achieve multifrequency operation in microstrip-based radiating structure design

Following recent findings on metamaterials, a miniaturized microstrip patch antenna loaded with a complementary split ring resonator (CSRR) was investigated for multiband operation. The proposed structure has a CSRR loaded in the base of the antenna to improve its performance and to make it a metamaterial. Metamaterials exhibit qualitatively new electromagnetic response functions that cannot be found in nature. The CSRR-loaded base allows simultaneous operation over several frequencies. Here, a total of seven bands were achieved by loading the patch antenna with the CSRR. The seven bands were centered around frequencies of 4.33 GHz, 5.29 GHz, 6.256 GHz, 7.066 GHz, 7.846 GHz, 8.86 GHz, and 9.75 GHz. Design results were obtained by using a high-frequency structure simulator that is used for simulating microwave passive components.

Enhanced bandwidth and gain of compact microstrip antennas loaded with multiple corrugated split ring resonators

Abstract We present microstrip-based radiating structures loaded with multiple corrugated and non-corrugated split-ring resonator (SRR) metamaterials. We analyze how the change in gap spacing between multiple corrugated and non-corrugated SRRs can improve the bandwidth and gain performance compared to conventional SRR antenna designs. Regarding the corrugated designs, square teeth have been added to the outer edges of SRR rings. The microstrip antenna performance loaded with eight different SRR loads is analyzed. By changing the gap between the multiple SRR rings, the radiating response of the proposed antenna designs can be improved. Corrugated SRRs are also found to strongly improve the performance of conventional non-corrugated SRR-loaded antenna designs. The reflection coefficient, bandwidth, and radiation pattern results are presented and compared to previous relevant metamaterial microstrip antenna works. The highest obtained bandwidth is 420 MHz, which is achieved by three square teeth SRRs. The highest calculated gain is 7 dB and is achieved by loading two square teeth SRRs. The proposed antenna design can be tuned to different frequency bands by embedding microelectromechanical system switches in SRRs’ gaps. The proposed antennas have compact size combined with high bandwidth and gain performance.
