A Metamaterial-Based Handset Antenna with the SAR Reduction

A Metamaterial-Based Handset Antenna with the SAR Reduction

A method to reduce the specific absorption rate(SAR) of the antenna for WiMAX mobile communication is proposed in this paper. The SAR reduction is achieved by miniaturizing the physical size of the antenna for the given resonance frequency by devising a metamaterial-composite rightand left-handed(CRLH) configuration-based radiator much smaller than the quarter-guided wavelength adopted a lot in...

Evaluating the deformation monitoring capability of a ground based SAR system with MIMO antenna

By increasing the applicability of ground-based SAR (GBSAR) systems in geoscience and remote sensing, the development and evaluation of new systems have gained attention. GBSAR systems can be utilized for monitoring areas that are hard to or cannot be seen by the airborne or spaceborne systems. Furthermore, they have better spatial and temporal resolutions and are cost-effective and easy to imp...

Metamaterial Based Multiple Frequency Antenna

Antennas that are electrically small, efficient and have significant bandwidth would fill many needs of new generation communications systems if antenna engineers could reconcile these usually contradictory requirements. The introduction of the so-called metamaterials (MTMs), artificial materials which have engineered electromagnetic responses that are not readily available in nature, has provi...

Analysis of Metamaterial Based Microstrip Array Antenna

Design of Metamaterial Based Microstrip Antenna With Multiband Frequency Application

This paper introduced a new low cost, compact and robust microstrip antenna based on metamaterial split ring resonator property to replace the existed antenna by small size and multiband Frequency antenna. The proposed antenna is designed with multi rectangular patches and simulated for different frequency. By using the metamaterial property, the bandwidth of the antenna has been improved. The ...
