The proposed antenna exhibits broad operating bandwidth, high gain, and high efficiency characteristics due to the suggested modifications in the antenna geometry. The suggested circular patch is modified by introducing slots in the form of a tree-shaped fractal structure, and the partial ground plane is modified by incorporating a narrow rectangular slot. The proposed antenna is designed on an FR4 substrate of [Formula: see text][Formula: see text]mm<jats:sup>3<\/jats:sup>. The prototype of the proposed antenna has been fabricated and tested to justify the simulation results. The measurement results are in good agreement with the simulation that validates the multi-broadband design approach of the proposed fractal antenna. As per the measurement results, the proposed antenna operates at four distinct bands with [Formula: see text]10[Formula: see text]dB impedance bandwidths of 600[Formula: see text]MHz (2.2\u20132.8) GHz, 1070[Formula: see text]MHz (3.3\u20134.37) GHz, 2550[Formula: see text]MHz (4.75\u20137.3) GHz, and 2200[Formula: see text]MHz (9.7\u201311.9) GHz. Furthermore, a high peak gain of 10.23[Formula: see text]dB and a peak radiation efficiency of 96.65% are recorded for the suggested fractal antenna. The suggested compact bandwidth enhanced multi-band antenna can be useful for several wireless communication systems such as wireless fidelity (Wi-Fi), wireless local area network (WLAN), Bluetooth, long-term evolution (LTE), C, S and X bands. <\/jats:p>","DOI":"10.1142\/s0218126622502048","type":"journal-article","created":{"date-parts":[[2022,4,21]],"date-time":"2022-04-21T09:00:26Z","timestamp":1650531626000},"source":"Crossref","is-referenced-by-count":9,"title":["A Compact Planar Multi-Resonant Multi-Broadband Fractal Monopole Antenna for Wi-Fi, WLAN, Wi-MAX, Bluetooth, LTE, S, C, and X Band Wireless Communication Systems"],"prefix":"10.1142","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1236-5763","authenticated-orcid":false,"given":"Ibrahime Hassan","family":"Nejdi","sequence":"first","affiliation":[{"name":"Laboratory of Automatics, Energy Conversion and Microelectronics, Faculty of Sciences and Technology, Sultan Moulay Slimare University, Campus Mghilla, BP 523, Beni-Mellal 23000, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sudipta","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, IMPS College of Engineering and Technology, Nityanandapur, P.O-Chandipur (Kazigram), Malda 732103, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youssef","family":"Rhazi","sequence":"additional","affiliation":[{"name":"Laboratory of Automatics, Energy Conversion and Microelectronics, Faculty of Sciences and Technology, Sultan Moulay Slimare University, Campus Mghilla, BP 523, Beni-Mellal 23000, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boddapati Taraka Phani","family":"Madhav","sequence":"additional","affiliation":[{"name":"Department of Electronics & Communication Engineering, Koneru Lakshmaiah Education Foundation, Green Fields, Vaddeswaram, Guntur 522502, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seddik","family":"Bri","sequence":"additional","affiliation":[{"name":"Material and Instrumentations Group, Electrical Engineering Department, Rue d\u2019Agouray, N6, Meknes 50040, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustapha","family":"Aitlafkih","sequence":"additional","affiliation":[{"name":"Laboratory of Automatics, Energy Conversion and Microelectronics, Faculty of Sciences and Technology, Sultan Moulay Slimare University, Campus Mghilla, BP 523, Beni-Mellal 23000, Morocco"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2022,4,20]]},"reference":[{"key":"S0218126622502048BIB001","doi-asserted-by":"publisher","DOI":"10.1002\/mop.28027"},{"key":"S0218126622502048BIB002","doi-asserted-by":"publisher","DOI":"10.1515\/freq-2020-0012"},{"key":"S0218126622502048BIB003","doi-asserted-by":"publisher","DOI":"10.1007\/s10825-017-1100-x"},{"key":"S0218126622502048BIB004","doi-asserted-by":"publisher","DOI":"10.2528\/PIERB15090905"},{"key":"S0218126622502048BIB005","doi-asserted-by":"publisher","DOI":"10.1002\/mop.28936"},{"key":"S0218126622502048BIB006","doi-asserted-by":"publisher","DOI":"10.1109\/LAWP.2014.2383441"},{"key":"S0218126622502048BIB007","doi-asserted-by":"publisher","DOI":"10.1002\/mop.26852"},{"key":"S0218126622502048BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/LAWP.2015.2406391"},{"key":"S0218126622502048BIB009","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2015.2389219"},{"key":"S0218126622502048BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2015.2452954"},{"key":"S0218126622502048BIB011","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-017-4500-0"},{"key":"S0218126622502048BIB012","first-page":"2249","volume":"8","author":"Garhwal A.","year":"2019","journal-title":"Int.
