A shared-aperture configuration comprising four Vivaldi elements for orthogonal polarizations is designed to reduce the low-end operating frequency and improve the port isolation with a compact antenna size. The directivity of the antenna is enhanced by the oblique position of the radiators and the implementation of a square loop reflector. Experimental results demonstrate that the antenna has very good impedance matching, port isolation, and dual-polarized radiation performance, with low dispersion characteristics across band of interest from 0.4 GHz to 3.0 GHz. GPR measurements with the designed antenna show that the antenna maintains good detection capability even for objects buried in a highly conductive soil.<\/jats:p>","DOI":"10.3390\/s21020503","type":"journal-article","created":{"date-parts":[[2021,1,12]],"date-time":"2021-01-12T20:11:31Z","timestamp":1610482291000},"page":"503","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Compact Dual-Polarized Vivaldi Antenna with High Gain and High Polarization Purity for GPR Applications"],"prefix":"10.3390","volume":"21","author":[{"given":"Hai-Han","family":"Sun","sequence":"first","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Ave, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yee Hui","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Ave, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenhao","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Ave, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lai Fern","family":"Ow","sequence":"additional","affiliation":[{"name":"Centre for Urban Greenery and Ecology, National Parks Board, 1 Cluny Rd, Singapore 259569, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2771-4877","authenticated-orcid":false,"given":"Mohamed Lokman Mohd","family":"Yusof","sequence":"additional","affiliation":[{"name":"Centre for Urban Greenery and Ecology, National Parks Board, 1 Cluny Rd, Singapore 259569, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulkadir C.","family":"Yucel","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, 50 Nanyang Ave, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1056","DOI":"10.1109\/TAP.2017.2786295","article-title":"Wideband Reflector-Backed Folded Bowtie Antenna for Ground Penetrating Radar","volume":"66","author":"Serhir","year":"2017","journal-title":"IEEE Trans.
