The overall geometry of the proposed antenna is 12\u00d718\u00d70.8\u200amm\n 3<\/jats:sup>\n . The designed structure is obtained by placing a simple modified circular robotic structure patch with dielectric constant (\n \u025b<\/jats:italic>\n \n r<\/jats:italic>\n <\/jats:sub>\n ) and dissipation factor (tan\n \u03b4<\/jats:italic>\n ) of 4.4 and 0.02, respectively, on the FR4 substrate. In this document, we examine the design technique, complexity, overall geometric parameters, substrate used, feed technique and performance analysis of the proposed antenna. The semi-grounded radiating patch design is primarily suitable for cellular vehicle applications and anything below 7\u200aGHz (C \u2013 V2X) (IEEE 802.11p standard) and WIFI enhanced 3rd version (IEEE 802.11ac standard). Simulation results for the proposed antenna were generated with a Radio Frequency Structure Simulator (HFSS) and measurements were obtained with a Rohde and Schwarz ZNB 20 network analyzer. Simulation and measurement results are measured in terms of S11, VSWR, bandwidth, gain, directivity, efficiency and radiation pattern. Antenna results show good agreement and can be used for C \u2013 V2X, WIFI Extended 3rd Version and satellite communications.\n <\/jats:p>","DOI":"10.3233\/rft-230043","type":"journal-article","created":{"date-parts":[[2024,6,28]],"date-time":"2024-06-28T14:13:24Z","timestamp":1719584004000},"page":"3-18","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Compact Ultra Wide band Modified Circular Robo type Antenna for C \u2013 V2X application"],"prefix":"10.1177","volume":"15","author":[{"given":"Ramya","family":"Vasudevan","sequence":"first","affiliation":[{"name":"Saveetha School of Engineering"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Nagaraju","sequence":"additional","affiliation":[{"name":"Saveetha School of Engineering"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,2]]},"reference":[{"key":"e_1_3_1_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/inventions5010011-1"},{"key":"e_1_3_1_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/jsan9020022-2"},{"key":"e_1_3_1_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00542-020-05127-7-3"},{"key":"e_1_3_1_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/jiot.2020.2974823-4"},{"key":"e_1_3_1_6_1","doi-asserted-by":"publisher","DOI":"10.2528\/pierl22010305-5"},{"key":"e_1_3_1_7_1","doi-asserted-by":"publisher","DOI":"10.3390\/mi11090828-6"},{"key":"e_1_3_1_8_1","doi-asserted-by":"publisher","DOI":"10.2528\/pierc21010505-7"},{"key":"e_1_3_1_9_1","doi-asserted-by":"publisher","DOI":"10.3233\/rft-190206-8"},{"key":"e_1_3_1_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/access.2019.2919489-9"},{"key":"e_1_3_1_11_1","doi-asserted-by":"publisher","DOI":"10.3390\/s18030911-10"},{"key":"e_1_3_1_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-16-9781-4_15-11"},{"key":"e_1_3_1_13_1","doi-asserted-by":"publisher","DOI":"10.1109\/access.2019.2949683-12"},{"key":"e_1_3_1_14_1","doi-asserted-by":"publisher","DOI":"10.2528\/pierc19112005-13"},{"key":"e_1_3_1_15_1","doi-asserted-by":"publisher","DOI":"10.1109\/ic-etite47903.2020.374-14"},{"key":"e_1_3_1_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2020.153260-15"},{"key":"e_1_3_1_17_1","doi-asserted-by":"publisher","DOI":"10.3390\/app10176001-16"},{"key":"e_1_3_1_18_1","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/8475621-17"},{"key":"e_1_3_1_19_1","doi-asserted-by":"publisher","DOI":"10.1109\/icacrs55517.2022.10029330-18"},{"key":"e_1_3_1_20_1","doi-asserted-by":"publisher","DOI":"10.2528\/pierc22060202-19"},{"key":"e_1_3_1_21_1","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2018.2828433-20"}],"container-title":["International Journal of RF Technologies"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/RFT-230043","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.3233\/RFT-230043","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/RFT-230043","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T04:44:50Z","timestamp":1777610690000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/RFT-230043"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,2]]},"references-count":20,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,2]]}},"alternative-id":["10.3233\/RFT-230043"],"URL":"https:\/\/doi.org\/10.3233\/rft-230043","relation":{},"ISSN":["1754-5730","1754-5749"],"issn-type":[{"value":"1754-5730","type":"print"},{"value":"1754-5749","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,2]]}}}
