SAR and radiation characteristics of dipole antenna above finite EBG substrate in presence of cubic head model
The present study investigates the performance of a dipole antenna above different electromagnetic band-gap (EBG) substrate for realizing a low specific absorption rate (SAR) antenna. We then investigate the effect of the number of unit cell of the EBG substrate on the antenna performance. The substrate with 24(4×6) EBG patches is considered as a reference. The dipole antenna above a substrate with sixteen EBG unit cells was shown to provide comparable SAR reduction and improved radiation efficiency as compared with the reference structure. A dielectric substrate with further reduced number of EBG patches did not provide sufficient SAR reduction and behave properly as a periodic structure.
