Imaging plays a key role in diagnosing and managing athletes with muscle injuries, but there are several problems with conventional imaging modalities with respect to cost and availability. We hypothesized that microwave imaging could provide improved availability and lower costs and lead to improved and more accurate diagnostics. In this paper, a semicircular microwave imaging array with eight antennae was investigated. A key component in this system is the novel antenna design, which is based on a monopole antenna and a lossy gel. The purpose of the gel is to reduce the effects of multipath signals and improve the imaging quality. Several different gels have been manufactured and evaluated in imaging experiments. For comparison, corresponding simulations were performed. The results showed that the gels can effectively reduce the multipath signals and the imaging experiments resulted in significantly more stable and repeatable reconstructions when a lossy gel was used compared to when an almost non-lossy gel was used.<\/jats:p>","DOI":"10.3390\/s22114121","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:30:06Z","timestamp":1653964206000},"page":"4121","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Microwave Antenna System for Muscle Rupture Imaging with a Lossy Gel to Reduce Multipath Interference"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2422-8029","authenticated-orcid":false,"given":"Laura","family":"Guerrero Orozco","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Chalmers University of Technology, 41296 Gothenburg, Sweden"},{"name":"MedTech West, Sahlgrenska University Hospital, 41345 Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars","family":"Peterson","sequence":"additional","affiliation":[{"name":"Sahlgrenska Academy, University of Gothenburg, 40530 Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9858-1688","authenticated-orcid":false,"given":"Andreas","family":"Fhager","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Chalmers University of Technology, 41296 Gothenburg, Sweden"},{"name":"MedTech West, Sahlgrenska University Hospital, 41345 Gothenburg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,29]]},"reference":[{"key":"ref_1","unstructured":"Fear, E., Low, A., Sill, J., and Stuchly, M.
