It consists of a line source generator (LSG) on the bottom surface, a spherical-wave to plane-wave transforming part on the middle layer, and CTS radiators on the top surface. Particularly, the LSG has four SIW-based H-plane horns, and a chip is integrated to switch among the two pairs of horns, so as to transfer the quasi-TEM waves on the bottom surface by a \u00b110\u00b0 deflection angle to the middle layer for the CTS radiators on the top surface, resulting in four reconfigurable scanning beams with 10\u00b0 for two polarizations. The measurements show that it realizes four reconfigurable beams with a 25.8 dBi gain at 24 GHz, verifying the design. The proposed antenna takes into account the advantages of reconfigurable multi-beam, dual polarization, low side lobes, low profile, and high gain, which can be applied to K-band sensing, especially for wind profile radars.<\/jats:p>","DOI":"10.3390\/s22093563","type":"journal-article","created":{"date-parts":[[2022,5,8]],"date-time":"2022-05-08T23:27:25Z","timestamp":1652052445000},"page":"3563","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Low-Profile SIW-Based CTS Array with Reconfigurable Four Beams and Dual Polarizations for K-Band Sensing"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1828-5214","authenticated-orcid":false,"given":"Yitong","family":"Jin","sequence":"first","affiliation":[{"name":"School of Communication & Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanqing","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Communication & Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4141-3090","authenticated-orcid":false,"given":"Yafei","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Communication & Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziwen","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Communication & Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Communication & Information Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Communication & 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":"School of Communication & Information Engineering, Shanghai University, Shanghai 200444, China"},{"name":"Suzhou Dufeng Technology Co., Ltd., Suzhou 215028, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"873","DOI":"10.1002\/met.1507","article-title":"Validation of the 1290 MHz wind profiler at Payerne, Switzerland, using radiosonde GPS wind measurements","volume":"22","author":"Haefele","year":"2016","journal-title":"Met.
