This technique offers valuable insights into molecular dynamics, structure, and interactions. A uniform magnetic field for spin excitation is generated by coupling two elliptical coils in a Helmholtz arrangement. The proposed coil stands out as an innovative alternative to traditional coils due to its improved efficiency, precise design, and reduced weight and spatial requirements. This work focuses primarily on the results obtained from finite element method (FEM) simulations. These simulations demonstrate a magnetic field uniformity of 92% across a broad frequency range (1\u201310\u2009MHz), achieved through optimized tuning and matching capacitors. The maximum uniform magnetic flux density recorded within this frequency range is 220\u2009\u03bcT. Furthermore, S11 and S21 parameters, along with the electric and magnetic field distributions, are calculated and analyzed to characterize RF signal interaction with the system. A detailed analysis of the S\u2010parameters reveals optimal coil matching and tuning, minimizing energy losses. Ultimately, these results confirm the suitability of the proposed coil for portable NMR spectrometers, highlighting the simulation\u2010driven design approach. This innovative design, with its significantly reduced weight, size, and manufacturing cost, promises considerable advancements in portable NMR spectroscopy.<\/jats:p>","DOI":"10.1002\/cta.4491","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T19:52:38Z","timestamp":1741722758000},"page":"5816-5826","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Planar Elliptical Coil Design With Helmholtz Structure Having a Uniform Magnetic Field for Nuclear Magnetic Resonance Spectroscopy"],"prefix":"10.1002","volume":"53","author":[{"given":"Mostafa","family":"Noohi","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering Sahand University of Technology  Tabriz Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5045-0101","authenticated-orcid":false,"given":"Hassan","family":"Faraji Baghtash","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering Sahand University of Technology  Tabriz Iran"}]},{"given":"Habib","family":"Badri Ghavifekr","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering Sahand University of Technology  Tabriz Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9697-4552","authenticated-orcid":false,"given":"Ali","family":"Mirvakili","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering Yazd University  Yazd Iran"}]}],"member":"311","published-online":{"date-parts":[[2025,3,2]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11220-024-00465-6"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1155\/2022\/5705637"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/ma13071694"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2016.2591551"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2022.3187041"},{"key":"e_1_2_7_7_1","doi-asserted-by":"crossref","unstructured":"C.Li X.Liu J.Yao B.Gao andK.Liu \u201cOpen Nuclear Magnetic Resonance Instrument Research for Intracranial Detection \u201d in2017 International Conference on Computer Systems Electronics and Control (ICCSEC) (2017).","DOI":"10.1109\/ICCSEC.2017.8446871"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-99-0546-1_8"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmr.2023.107510"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2020.3001058"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2019.2956682"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2018.2887274"},{"issue":"5","key":"e_1_2_7_13_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1109\/TASC.2019.2902802","article-title":"Design of NMR RF Probe Constructed With High\u2010Temperature Superconducting Elliptical\u2013Coupled Resonators","volume":"29","author":"Sekiya N.","year":"2019","journal-title":"IEEE Transactions on Applied Superconductivity"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2016.2579158"},{"key":"e_1_2_7_15_1","doi-asserted-by":"crossref","unstructured":"M.Gupta \u201cLow Cost RF Planar Spiral Coil for Portable NMR Applications \u201d in2018 Second International Conference on Electronics Communication and Aerospace Technology (ICECA) (2018).","DOI":"10.1109\/ICECA.2018.8474762"},{"key":"e_1_2_7_16_1","doi-asserted-by":"crossref","unstructured":"M.Gupta C.Safvan K.Singh andD.Lobiyal \u201cModeling and Simulation of on\u2010Chip Probe for Portable NMR Applications in2018 Progress in Electromagnetics Research Symposium (PIERS\u2010Toyama) (2018).","DOI":"10.23919\/PIERS.2018.8597770"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1109\/TASC.2005.849582"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1109\/TASC.2014.2368778"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ppnp.2021.103930"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2018.2870361"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1039\/D3CP05556F"},{"volume-title":"High\u2010Resolution NMR Techniques in Organic Chemistry","year":"2016","author":"Claridge T.
