The antenna model had an overall dimension of 70 \u00d7 31 \u00d7 1.6 mm3 with etched T-slots and L-slots for dual band resonance. The main objective of this work was to enhance the gain performance characteristic at the selected dual band frequencies of 0.915 GHz and 2.45 GHz. Initially, it achieved a narrow bandwidth of 0.018 GHz with a gain of 1.53 dBi at a lower frequency, and 0.13 GHz of bandwidth featuring 4.49 dBi of gain at a higher frequency. The antenna provided an impedance bandwidth of 2% (0.905\u20130.923 GHz) and 5% (2.382\u20132.516 GHz) at two resonating frequencies. The antenna was integrated with a designed novel AMC structure to enhance the gain in CST Microwave Studio software with the finite integration method. The characteristic features of the AMC unit cell were observed at 0.915 GHz and 2.45 GHz frequencies and after antenna integration, the final prototype achieved a gain of 2.87 dBi at 0.915 GHz and 6.8 dBi at 2.45 GHz frequencies.<\/jats:p>","DOI":"10.3390\/s22208065","type":"journal-article","created":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T10:09:23Z","timestamp":1666606163000},"page":"8065","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["A Metamaterial Inspired AMC Backed Dual Band Antenna for ISM and RFID Applications"],"prefix":"10.3390","volume":"22","author":[{"given":"Md.","family":"Najumunnisa","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, Koneru Lakshmaiah Education Foundation, Vaddeswaram 522302, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ambadapudi Srinivasa Chandrasekhara","family":"Sastry","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Koneru Lakshmaiah Education Foundation, Vaddeswaram 522302, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6893-6978","authenticated-orcid":false,"given":"Boddapati Taraka Phani","family":"Madhav","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Koneru Lakshmaiah Education Foundation, Vaddeswaram 522302, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4555-7438","authenticated-orcid":false,"given":"Sudipta","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, IMPS College of Engineering and Technology, Malda 732103, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9730-4622","authenticated-orcid":false,"given":"Niamat","family":"Hussain","sequence":"additional","affiliation":[{"name":"Department of Smart Device Engineering, Sejong University, Seoul 05006, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1745-0270","authenticated-orcid":false,"given":"Syed Samser","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, University Institute of Technology, Burdwan 713104, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5854-8197","authenticated-orcid":false,"given":"Muhammad","family":"Aslam","sequence":"additional","affiliation":[{"name":"Department of Artificial Intelligence, Sejong University, Seoul 05006, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1240","DOI":"10.1038\/s41598-018-19705-3","article-title":"Dual Band Metamaterial Antenna For LTE\/Bluetooth\/WiMAX System","volume":"8","author":"Hasan","year":"2018","journal-title":"Sci.
