The antenna geometry included two metallic plates with extended hook-shaped strips at its principal diagonal position, and two corners of truncated metallic plates at the secondary diagonal position. The pair of metallic vias connected the modified strips to the ground plane to create the magnetic dipole. The L-shaped probe feed between the strips was used to excite the antenna. The antenna showed stable gain and wideband characteristics. The simulated and measured results showed that the proposed CP ME dipole antenna had an overlapping (|S11|&lt; \u221210 dB impedance and 3 dB axial ratio) bandwidth of 18.1% (25\u201330 GHz), covering the frequency bands dedicated for 5G new radio communications. Moreover, an average gain of 8 dBic was achieved by the antenna throughout the operating bandwidth. The measured data verified the design concept, and the proposed antenna had a small footprint of 0.83 \u03bbo \u00d7 0.83 \u03bbo \u00d7 0.125 \u03bbo (\u03bbo is free space wavelength at the lowest operating frequency), suitable for its application in 5G smart devices and sensors.<\/jats:p>","DOI":"10.3390\/s22062338","type":"journal-article","created":{"date-parts":[[2022,3,20]],"date-time":"2022-03-20T21:37:17Z","timestamp":1647812237000},"page":"2338","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["A Wideband Circularly Polarized Magnetoelectric Dipole Antenna for 5G Millimeter-Wave Communications"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4757-3474","authenticated-orcid":false,"given":"Hussain","family":"Askari","sequence":"first","affiliation":[{"name":"Department of Information and Communication, Chungbuk National University, Cheongju 28644, Korea"}]},{"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"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2995-6551","authenticated-orcid":false,"given":"Md.
