The unit element array is a flower-shaped DRA fed with a cross slot. To obtain circular polarization, a sequential network combined with the cross slots is used to feed the 2\u00d72 array. The prototype of the proposed antenna array is fabricated and measured to obtain a wide resonance bandwidth from 27 GHz to 38 GHz frequency band. Furthermore, this left-hand polarized antenna array has achieved a peak gain of 9.5 dBi with 3-dB axial ratio at 30 GHz. The proposed DRA array with wideband resonance and gain bandwidth has the potential to be used for millimeter-wave wireless communications at the 30 GHz band.<\/jats:p>","DOI":"10.3390\/s21113614","type":"journal-article","created":{"date-parts":[[2021,5,24]],"date-time":"2021-05-24T00:01:20Z","timestamp":1621814480000},"page":"3614","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Wideband Circular Polarized Dielectric Resonator Antenna Array for Millimeter-Wave Applications"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7447-8830","authenticated-orcid":false,"given":"Arun","family":"Kesavan","sequence":"first","affiliation":[{"name":"Centre\u2014Energie Mat\u00e9riaux et T\u00e9l\u00e9communications, Institut National de la Recherche Scientifique, Montr\u00e9al, QC H5A1K6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3629-2987","authenticated-orcid":false,"given":"Mu\u2019ath","family":"Al-Hassan","sequence":"additional","affiliation":[{"name":"Al Ain University of Science and Technology, Abu Dhabi 64141, United Arab Emirates"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ismail","family":"Ben Mabrouk","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Durham University, Durham DH1 3LE, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tayeb A.","family":"Denidni","sequence":"additional","affiliation":[{"name":"Centre\u2014Energie Mat\u00e9riaux et T\u00e9l\u00e9communications, Institut National de la Recherche Scientifique, Montr\u00e9al, QC H5A1K6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"335","DOI":"10.1109\/ACCESS.2013.2260813","article-title":"Millimeter Wave Mobile Communications for 5G Cellular: It Will Work!","volume":"1","author":"Rappaport","year":"2013","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1109\/TAP.2015.2499750","article-title":"High Gain and Low Cost Differentially Fed Circularly Polarized Planar Aperture Antenna for Broadband Millimeter-Wave Applications","volume":"64","author":"Bisharat","year":"2016","journal-title":"IEEE Trans.
