Abstract

The Advances in the biomedical applications demands an antenna having highefficiency and gain, low return losses and Specific Absorption Ratio (SAR) to beassociated with the wearable and implantable devices for the accurate data transferwithout any data drift. For this, multi-band MIMO (multi-input multi output)applications, the antenna design with the target parameters is a challenging task toestablish a rich and reliable wireless communication setup with the monitoring systemin SHM of both biomedical and industrial sectors. Higher SAR will create the hazardsto the human body. The gain of the antenna and return loss figures depends on thesignal loss in the human tissues. Another important design challenge is the antennasize, which should be convenient to carry. Usually, Micro strip patch antenna is usingfor such type of applications as it satisfies most of the design parameters. But thebandwidth and gain of MSP are very limited. Hence there is huge scope to enhancethe gain and bandwidth of the micro strip patch antenna to fit for the biomedicalinvasive applications. Artificial materials having negative permittivity andpermeability will yield a negative refractive index will do better than the existingmaterials in the antenna design for the ISM band(2.45-5.8GHz) and satellites (11-13GHz).
