Such an antenna is constructed on the two sides of a square substrate. The antenna consists of a wideband monopolar patch antenna fed by a probe in the center and two sets of arc\u2010hook\u2010shaped branches. The monopolar patch antenna is loaded by a set of conductive shorting vias to achieve a wideband vertically polarized electric field. Two sets of arc\u2010hook\u2010shaped parasitic branches connected to the patch and ground plane can generate a horizontally polarized electric field. To further increase the bandwidth of the horizontally polarized electric field, two types of arc\u2010hook\u2010shaped branches with different sizes are used, which can generate another resonant frequency. When the parameters of the arc\u2010hook\u2010shaped branches are reasonably adjusted, a 90\u00b0 phase difference can be generated between the vertically polarized electric field and the horizontally polarized electric field, so that the antenna can produce a wideband CP radiation pattern with a conical beam. The proposed antenna has a wide impedance bandwidth (\u2223<jats:italic>S<\/jats:italic><jats:sub>11<\/jats:sub> | &lt;\u221210\u2009dB) of 35.6% (4.97\u20107.14\u2009GHz) and a 3\u2009dB axial ratio (AR) bandwidth at phi = 0<jats:sup>\u00b0<\/jats:sup> and theta = 35<jats:sup>\u00b0<\/jats:sup> of about 30.1% (4.97\u20106.73\u2009GHz). Compared with the earlier reported conical\u2010beam CP antennas, an important feature of the proposed antenna is that the AR bandwidth is completely included in the impedance bandwidth, that is, the overlap bandwidth of \u2223<jats:italic>S<\/jats:italic><jats:sub>11<\/jats:sub> | &lt;\u221210\u2009dB and AR &lt; 3\u2009dB is 30.1%. Moreover, the stable omnidirectional conical\u2010beam radiation patterns can be maintained within the whole operational bandwidth.<\/jats:p>","DOI":"10.1155\/2021\/6648887","type":"journal-article","created":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T01:31:29Z","timestamp":1614562289000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Low\u2010Profile Circularly Polarized Conical\u2010Beam Antenna with Wide Overlap Bandwidth"],"prefix":"10.1155","volume":"2021","author":[{"given":"Wei","family":"He","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8564-5355","authenticated-orcid":false,"given":"Yejun","family":"He","sequence":"additional","affiliation":[]},{"given":"Long","family":"Zhang","sequence":"additional","affiliation":[]},{"given":"Sai-Wai","family":"Wong","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8093-9776","authenticated-orcid":false,"given":"Wenting","family":"Li","sequence":"additional","affiliation":[]},{"given":"Amir","family":"Boag","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,2,28]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/lawp.2013.2296324"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2003.809058"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/lawp.2009.2023545"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.1984.1143455"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1049\/el:19900418"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2017.2784452"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2019.2941551"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2013.2253302"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/LAWP.2018.2856504"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/LAWP.2017.2752358"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2017.2754403"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1109\/lawp.2009.2028909"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1109\/LAWP.2014.2369515"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2012.2220101"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2019.2916737"},{"key":"e_1_2_8_16_2","doi-asserted-by":"crossref","unstructured":"SharmaT.
