Dual Band Antenna

A simple and successful dual band patch linear polarized rectangular antenna design is presented. The dual band antenna is designed etching a complementary rectangular split-ring resonator in the patch of a conventional rectangular patch antenna. Furthermore, a parametric study shows the influence of the location of the CSRR particle on the radiation characteristics of the dual band antenna. Going further, a miniaturization of the conventional rectangular patch antenna and an enhancement of the complementary split-ring resonator resonance gain versus the location of the CSRR on the patch are achieved. The dual band antenna design has been made feasible due to the quasistatic resonance property of the complementary split-ring resonators. The simulated results are compared with measured data and good agreement is reported.

Dual Band Antenna

In this paper, a novel compact microstrip patch antenna is proposed for Wi- Fi and WiMAX bands. To achieve miniaturization the dimensions of the square radiating patch are chosen with reference to the high frequency band (3.3 GHz). The dual band is achieved by loading a Complementary Split Ring Resonator (CSRR) into the radiating patch. The left handed nature of the CSRR is the cause for low frequency band (2.4 GHz). To improve the return loss bandwidth and axial ratio bandwidth at upper band the fractal concept is introduced along the edges of the square patch. Thus a low volume dual band antenna is simulated using HFSS. A comparison with measured data is also presented. The fabricated antenna is found to be occupying 25% less volume (with reference to 2.4 GHz) than existing antennas which is mainly due to the blending of the two recent concepts ‘metamaterials and fractals’.

Dual Substrate

The authors have attempted to influence an embedded square split ring resonator (SSRR) response in a stacked non-homogeneous substrate to demonstrate a quad-band antenna. The purpose is to produce multiband operations of a microstrip patch antenna. The highlighted factor is the effect of embedding an SSRR and the differing relative permittivity of the substrate on the side length of the SSRR. The analysis shows that a non-homogeneous dual substrate patch produces multiple bands compared to a single substrate patch antenna without any parameter change. A dual substrate antenna fabricated using FR4 and Rogers RT/Duroid 5880 copper clad sheets with a dimension of 85.6x54x0.908 mm3 (0.314λ0x0.198λ0x0.003λ0). The antenna resonates at 1.1, 2.45, 3.65 and 5.25 GHz in the L-, S- and C-bands. It is possible to employ the patch antenna in WLAN (dual-band) and WiMAX applications and suitable for mobile broadcast service at 1.1 GHz. The authors compare the simulated and measured results of a prototype in the article. The maximum measured gain is 5.48 dBi at 1.1 GHz and 4.025 dBi at 3.65 GHz. The measured bandwidth is 60 MHz (1.2%) at 5.25 GHz.
