The proposed antenna, implemented using a tightly coupled array, operates over roughly the X-K frequency band and is performant at 8 GHz\u201318.5 GHz. The antenna can scan to \u00b160 degrees in both the E- and H-planes. Compared to previous tightly coupled antennas with smaller element spacing, the antenna in this paper reaches 9.4 mm, which corresponds to 0.58\u00a0\u03bb of high frequency, suitable for engineering application conditions in production. The antenna can be soldered to BGA T\/R chips in this space. Additionally, to facilitate flexible assembly for large arrays, the antenna is manufactured modularly using four elements and its parasitic radiation is analyzed. Then, a method for repressing parasitic radiation is presented. Finally, the antenna is fabricated and measured in a microwave chamber, exhibiting an excellent pattern and scanning radiation. The measured performance agrees with the full-wave finite array simulations.<\/jats:p>","DOI":"10.3390\/s24113295","type":"journal-article","created":{"date-parts":[[2024,5,22]],"date-time":"2024-05-22T07:56:11Z","timestamp":1716364571000},"page":"3295","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Wide-Band Low-Profile Antenna for a High-Integration Phased Array System"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-6138-6878","authenticated-orcid":false,"given":"Haipeng","family":"Liu","sequence":"first","affiliation":[{"name":"School of Mechano-Electronic Engineering, Xidian University, Xi\u2019an 710071, China"},{"name":"Beijing Institute of Remote Sensing Equipment, Beijing 100039, China"}]},{"given":"Juan","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechano-Electronic Engineering, Xidian University, Xi\u2019an 710071, China"},{"name":"Beijing Institute of Remote Sensing Equipment, Beijing 100039, China"}]},{"given":"Jin","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Mechano-Electronic Engineering, Xidian University, Xi\u2019an 710071, China"}]},{"given":"Chunhui","family":"Han","sequence":"additional","affiliation":[{"name":"Beijing Institute of Remote Sensing Equipment, Beijing 100039, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7706-3627","authenticated-orcid":false,"given":"Bo","family":"Chen","sequence":"additional","affiliation":[{"name":"Beijing Institute of Remote Sensing Equipment, Beijing 100039, China"}]},{"given":"Yuhe","family":"Liu","sequence":"additional","affiliation":[{"name":"Beijing Institute of Remote Sensing Equipment, Beijing 100039, China"}]},{"given":"Yujie","family":"Xiang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Remote Sensing Equipment, Beijing 100039, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"364","DOI":"10.1109\/TAP.1983.1143030","article-title":"The wide-band matching area for a small antenna","volume":"31","author":"Wheeler","year":"1983","journal-title":"IEEE Trans.
