The system comprises an ultrawideband (UWB) pulse generator, breast phantoms, an antenna array, and the proposed receiver, which has a maximum input bandwidth of 18\u2009GHz with a minimum clock step of 10\u2009ps. The pulse generator outputs a monocycle pulse with a bandwidth of 0.50\u20135.25\u2009GHz. The breast phantoms include square and realistic breast models, with soybean oil as the fat medium. The antenna array is uniformly distributed around the breast phantom, sequentially transmitting pulse signals, and receives scattered signals. The receiver captures these signals and transmits them to a personal computer (PC) for data processing and image reconstruction. Measurements are taken with different types, sizes, and depths of tumor phantoms in breast models. A 5\u2010mm bacon target is successfully detected, with a relative error and coordinate error of 2.19% and 2.83\u2009mm, respectively. The signal\u2010to\u2010clutter ratio (SCR) and signal\u2010to\u2010mean ratio (SMR) are 2.90 and 8.35\u2009dB, respectively. It demonstrates that the designed UWB microwave detection system can identify small\u2010sized breast tumor targets and has the potential to replace large commercial and expensive instruments, enabling miniaturization and portability.<\/jats:p>","DOI":"10.1002\/cta.4536","type":"journal-article","created":{"date-parts":[[2025,3,28]],"date-time":"2025-03-28T00:37:36Z","timestamp":1743122256000},"page":"6130-6142","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Compact and Low\u2010Cost Ultrawideband Breast Tumor Microwave Detection System Based on an Equivalent Sampling Receiver"],"prefix":"10.1002","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-4562-2540","authenticated-orcid":false,"given":"Xuhui","family":"Zang","sequence":"first","affiliation":[{"name":"Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology, School of Microelectronics Tianjin University  Tianjin China"}]},{"given":"Xia","family":"Xiao","sequence":"additional","affiliation":[{"name":"Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology, School of Microelectronics Tianjin University  Tianjin China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9812-4188","authenticated-orcid":false,"given":"Guancong","family":"Liu","sequence":"additional","affiliation":[{"name":"Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology, School of Microelectronics Tianjin University  Tianjin China"}]},{"given":"Xiaofeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology, School of Microelectronics Tianjin University  Tianjin China"}]},{"given":"Huayang","family":"Zhou","sequence":"additional","affiliation":[{"name":"Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology, School of Microelectronics Tianjin University  Tianjin China"}]},{"given":"Takamaro","family":"Kikkawa","sequence":"additional","affiliation":[{"name":"Research Institute for Nanodevices Hiroshima University  Higashihiroshima Japan"}]}],"member":"311","published-online":{"date-parts":[[2025,3,25]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s44197-023-00176-3"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21583"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.breast.2022.08.010"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bspc.2022.104078"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.27795"},{"key":"e_1_2_8_7_1","first-page":"1","article-title":"Health\u2010Related Quality of Life in Breast Cancer Patients: Review of Reviews From 2008 to 2018","volume":"18","author":"Mokhatri\u2010Hesari P.","year":"2020","journal-title":"Health and Quality of Life Outcomes"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(11)61350-0"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejro.2023.100545"},{"issue":"3","key":"e_1_2_8_10_1","doi-asserted-by":"crossref","DOI":"10.1148\/radiol.213199","article-title":"Deep Learning to Simulate Contrast\u2010Enhanced Breast MRI of Invasive Breast Cancer","volume":"306","author":"Chung M.","year":"2022","journal-title":"Radiology"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.32887"},{"key":"e_1_2_8_12_1","first-page":"3775","volume-title":"36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society","author":"Bahrami H.","year":"2014"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-019-41124-1"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1109\/TMI.2012.2197218"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1088\/0031-9155\/37\/1\/014"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.3390\/s18092951"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.3390\/s20082390"},{"key":"e_1_2_8_18_1","doi-asserted-by":"crossref","first-page":"172297","DOI":"10.1109\/ACCESS.2024.3496117","article-title":"Microstrip Patch Antennas for Breast Tumor\/Cancer Cell Detection\u2013Challenges, Designs and Future Opportunities: A Review","volume":"12","author":"Mahfuz M.
