The proposed patch offers a wide simulated operating band that reaches 8.3 GHz, a simulated gain that varies between 2.47 and 7.73 dB throughout the operating range, and a high simulated efficiency that comes to 98% due to the modifications made to the antenna geometry. The modifications carried out on the antenna are composed of several stages, a circular ring extracted from a circular antenna in which four rings are integrated and, in each ring, four other rings are integrated with a reduction factor of 3\/8. To further improve the adaptation of the antenna, a modification of the shape of the ground plane is carried out. In order to test the simulation results, the prototype of the suggested patch was built and tested. The measurement results validate the suggested dual ultra-wideband antenna design approach, which demonstrates good compliance with the simulation. From the measured results, the suggested antenna with a compact volume of 40 \u00d7 24.5 \u00d7 1.6 mm3 asserts ultra-wideband operation with a measured impedance bandwidth of 7.33 GHz. A high measured efficiency of 92% and a measured gain of 6.52 dB is also achieved. The suggested UWB can effectively cover several wireless applications such as WLAN, WiMAX, and C and X bands.<\/jats:p>","DOI":"10.3390\/s23084172","type":"journal-article","created":{"date-parts":[[2023,4,24]],"date-time":"2023-04-24T03:04:08Z","timestamp":1682305448000},"page":"4172","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["UWB Circular Fractal Antenna with High Gain for Telecommunication Applications"],"prefix":"10.3390","volume":"23","author":[{"given":"Ibrahime Hassan","family":"Nejdi","sequence":"first","affiliation":[{"name":"Automatic and Energy Conversion (AEC) Faculty of Sciences and Technology, BP 523, Beni-Mellal 23000, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seddik","family":"Bri","sequence":"additional","affiliation":[{"name":"Material and Instrumentations Group, Electrical Engineering Department, ESTM Moulay Ismail University, BP 3103, Meknes 50040, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed","family":"Marzouk","sequence":"additional","affiliation":[{"name":"Microelectronics, Embedded Systems and Telecommunications (MiSET) Faculty of Sciences and Technology, BP 523, Beni-Mellal 23000, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3099-1752","authenticated-orcid":false,"given":"Sarosh","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering and Technology, Government College University Faisalabad (GCUF), Faisalabad 38000, Pakistan"},{"name":"Department of Signal Theory and Communications, Universidad Carlos III de Madrid (UC3M), 28911 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6327-8507","authenticated-orcid":false,"given":"Youssef","family":"Rhazi","sequence":"additional","affiliation":[{"name":"Microelectronics, Embedded Systems and Telecommunications (MiSET) Faculty of Sciences and Technology, BP 523, Beni-Mellal 23000, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustapha","family":"Ait Lafkih","sequence":"additional","affiliation":[{"name":"Automatic and Energy Conversion (AEC) Faculty of Sciences and Technology, BP 523, Beni-Mellal 23000, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1458-3898","authenticated-orcid":false,"given":"Yawar Ali","family":"Sheikh","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering and Technology, Government College University Faisalabad (GCUF), Faisalabad 38000, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4548-9765","authenticated-orcid":false,"given":"Adnan","family":"Ghaffar","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Auckland University of Technology, Auckland 1010, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2186-9883","authenticated-orcid":false,"given":"Mousa","family":"Hussein","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, United Arab Emirates University, Al Ain 15551, United Arab Emirates"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kirtania, S.G., Younes, B.A., Hossain, A.R., Karacolak, T., and Sekhar, P.K.
