This paper proposes a lens antenna operating at 24 GHz with four reconfigurable beams for wind profile radars. This lens antenna includes 2 \u00d7 2 corrugated horn antennas for radiating 24 GHz waves in two polarizations, and the dielectric lens for modulating four radiation beams with a high gain and low sidelobe. Experiments demonstrate that this lens antenna can realize reconfigurable beams with deflections of \u00b115\u00b0 in dual polarizations, meanwhile with the gain of 30.58 dBi and the sidelobe of \u221220 dB. This proposed lens antenna can be applied to mmWave wind profile radars of wind turbines for enhancing wind power efficiency.<\/jats:p>","DOI":"10.3390\/s22093148","type":"journal-article","created":{"date-parts":[[2022,4,21]],"date-time":"2022-04-21T03:46:11Z","timestamp":1650512771000},"page":"3148","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Lens Antenna with Reconfigurable Beams for mmWave Wind Profile Radar"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4141-3090","authenticated-orcid":false,"given":"Yafei","family":"Ding","sequence":"first","affiliation":[{"name":"Shanghai Institute for Advanced Communication and Data Science (SICS), School of Communication and Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziwen","family":"Zou","sequence":"additional","affiliation":[{"name":"Shanghai Institute for Advanced Communication and Data Science (SICS), School of Communication and Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Luo","sequence":"additional","affiliation":[{"name":"Shanghai Institute for Advanced Communication and Data Science (SICS), School of Communication and Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5841-9830","authenticated-orcid":false,"given":"Guangli","family":"Yang","sequence":"additional","affiliation":[{"name":"Shanghai Institute for Advanced Communication and Data Science (SICS), School of Communication and Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,20]]},"reference":[{"key":"ref_1","unstructured":"Edenhoffer, O.
