The antenna array includes a central microstrip line with a series of indirectly adjacent parasitic coupled trapezoidal patches periodically arranged on both sides. By precisely adjusting the gap between these parasitic patches and lines to control the normalized impedance of the radiating elements, it helps to achieve broadband and low sidelobe levels (SLLs) characteristics. To validate the proposed design, two antennas\u2014a 1\u2009\u00d7\u200916 linear array and an 8\u2009\u00d7\u200916 planar array based on the SIW feeding network\u2014are developed to operate within the 77\u2010 to 81\u2010GHz range. The measured SLLs are lower than \u221220\u2009dB, with measured gains exceeding 15 dBi for the 1\u2009\u00d7\u200916 array and 20\u2009dBi for the 8\u2009\u00d7\u200916 array across the 77\u2010 to 81\u2010GHz band. The impedance bandwidth of the 8\u2009\u00d7\u200916 planar array reaches 6.8% (76.2\u2009GHz\u201381.5\u2009GHz).<\/jats:p>","DOI":"10.1002\/cta.70163","type":"journal-article","created":{"date-parts":[[2025,10,3]],"date-time":"2025-10-03T10:27:37Z","timestamp":1759487257000},"page":"7373-7381","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Broadband
