Microstrip Patch

This article presents a proposal about an octagonal microstrip patch antenna (MPA) loaded with Split Ring Resonators (SRR) the antenna’s ground part. The antenna size reduction using multiband radiators will suits for miniaturization of day-to-day handheld devices. The dual band behaviour of the antenna will integrate more communication standard in one system which saves the installation space in the device. In this context, an octagonal antenna structure is conceived for a dual operational frequency of 5.63 GHz and 5.97 GHz. Hereby, a Co-planar Waveguide (CPW) structure is adapted to the octagonal patch and the structure has been observed by simulation analysis under HFSS platform. The overall geometry of the antenna is 30 x 26 x 1.6 mm3. The antenna feed using a microstrip for earning a better impedance matching between the antenna and transmission line. The antenna design provides a wider bandwidth of 580MHz and average gain of 3.25 dBm. The attainment of dual band operational frequencies is due to the CPW and SRR structure in the antenna design.

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.
