The antenna has a patch like radiation pattern in 3.5GHz WLAN band for OFF body communication whereas vertical monopole-like radiation pattern in 5.8 GHz ISM band for communicating with other sensors based ON body devices. The antenna is fabricated and tested over human hand. Due to the characteristic radiation pattern of the antenna at two operating frequencies, the antenna is found to be least coupled with the human body and thereby a low specific absorption rate (SAR) value of 0.21 W/Kg and 1.21 W/kg at two resonant frequencies. The simulation results were found to be in good agreement with the measurement results.","PeriodicalId":397541,"journal":{"name":"2017 IEEE Applied Electromagnetics Conference (AEMC)","volume":"405 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124358049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By engraving grooves on side-wall of the cylindrical DRA, the bandwidth and gain improved by 200% and 20%, respectively. It is observed that despite of isotropic dielectric material, the continuous disorder on the side-wall led the electromagnetic waves to penetrate out easily from the side-wall resulting improved performances.

The proposed antenna for single band is composed of a rectangular patch and bottom edges of patch made as tapered structure for better radiation. The same antenna has been modified for dual and triple bands of operation by inserting the square slot in the middle of the tapered patch and placing the rectangular radiator strip on top of the tapered radiator patch. A CPW feeding line and defective ground structure (DGS) are the key features of this antenna. A novelty of this designed antenna is able to propagate multichannel in the UWB range. The designed antennas are constructed on the substrate of FR4 with a planar size of 30mm χ 41mm with a thickness of 1.6mm.
