In this context, this paper\u2002proposes a nature inspired antenna design using sneezewort leaf shape geometry combined with DGS (defective ground structure) to improve bandwidth and radiation features. A partial ground, the proposed antenna is very compact in size 18\u2009\u00d7\u200919\u2009\u00d7\u20091.6 mm\n                    <jats:sup>3<\/jats:sup>\n                    (0.18\u03bb\u2009\u00d7\u20090.2\u03bb\u2009\u00d7\u20090.016\u03bb) and has a wideband operation,\u2002that is, 3.16\u20135.42\u00a0GHz. It shows wide impedance bandwidth of 55.96% and\u2002has a highest gain of 2.1 dBi. Due to its planar, lightweight and low-profile structure, the antenna is ideal for low-cost mass production and easy integration with emerging wireless and healthcare gadgets. The multifunctional antenna lends itself to varied uses such as sub-6\u00a0GHz 5G communication, high-speed Wi-Fi, near-field vehicular radar, and industrial ISM-band devices. Besides, the antenna clearly show good prospect for\u2002many biomedical diagnostic applications, such as breast, brain, skin, lung, heart and kidney abnormalities detection, temporomandibular joint (TMJ) disorders, typhoid, bone fracture, dengue, food contaminations and lately even COVID-19. A breast tumor detection\u2002proof-of-concept is demonstrated exclusively by simulation using a breast phantom, which demonstrates the antenna sensitivity to changes in dielectric properties. These results indicate that the proposed antenna\u2002could be potential for the wireless communication in the future and also in the medical applications. Experimental validation including\u2002studies on physical phantoms and clinical studies will be included in future work.\n                  <\/jats:p>","DOI":"10.1038\/s41598-026-51192-9","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T03:00:16Z","timestamp":1779073216000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A miniature bio-inspired antenna for sub-6\u00a0GHz consumer wireless and biomedical diagnostic applications"],"prefix":"10.1038","volume":"16","author":[{"given":"Tapan","family":"Nahar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanyog","family":"Rawat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vishal","family":"Das","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Parul","family":"Pathak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bal","family":"Virdee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sushil Kumar","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,5,18]]},"reference":[{"key":"51192_CR1","doi-asserted-by":"publisher","first-page":"103269","DOI":"10.1016\/j.rineng.2024.103269","volume":"24","author":"CJM Andrews","year":"2024","unstructured":"Andrews, C.
