This system is based on an H-shaped monopole antenna system that offers 200 MHz bandwidth ranges between 3.4\u20133.6 GHz, and the isolation between any two elements is well below \u221212 dB without using any decoupling structure. The proposed system is designed on a commercially available 0.8 mm-thick FR4 substrate. One side of the chassis is used to place the radiating elements, while the copper from the other side is being removed to avoid short-circuiting with other components and devices. This also enables space for other systems, sub-systems, and components. A prototype is fabricated and excellent agreement is observed between the experimental and the computed results. It was found that ECC is 0.2 for any two radiating elements which is consistent with the desirable standards, and channel capacity is 38 bps\/Hz which is 2.9 times higher than 4 \u00d7 4 MIMO configuration. In addition, single hand mode and dual hand mode analysis are conducted to understand the operation of the system under such operations and to identify losses and\/or changes in the key performance parameters. Based on the results, the proposed antenna system will find its applications in modern 5G handheld devices and internet of things with healthcare and high rate delivery. Besides that, its design simplicity will make it applicable for mass production to be used in industrial demands.<\/jats:p>","DOI":"10.3390\/s21217415","type":"journal-article","created":{"date-parts":[[2021,11,8]],"date-time":"2021-11-08T22:08:41Z","timestamp":1636409321000},"page":"7415","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":52,"title":["MIMO Antenna System for Modern 5G Handheld Devices with Healthcare and High Rate Delivery"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5004-9350","authenticated-orcid":false,"given":"Saad Hassan","family":"Kiani","sequence":"first","affiliation":[{"name":"Electrical Engineering Department, City University of Science and Information Technology, Peshawar 25000, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3209-6345","authenticated-orcid":false,"given":"Ahsan","family":"Altaf","sequence":"additional","affiliation":[{"name":"INZA Research Laboratory for Electromagnetic and Microwave Engineering, Multan 60600, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7139-7143","authenticated-orcid":false,"given":"Muhammad Rizwan","family":"Anjum","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, The Islamia University of Bahawalpur, Bahawalpur 63100, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7317-1615","authenticated-orcid":false,"given":"Sharjeel","family":"Afridi","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Sukkur IBA University, Sukkur 65200, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4487-7651","authenticated-orcid":false,"given":"Zulfiqar Ali","family":"Arain","sequence":"additional","affiliation":[{"name":"Department of Telecommunication Engineering, Mehran University of Engineering and Technology, Jomshoro 76062, Pakistan"},{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunication, Beijing 100876, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4179-230X","authenticated-orcid":false,"given":"Sadia","family":"Anwar","sequence":"additional","affiliation":[{"name":"Department of Business Development and Technology, Aarhus University, 8000 Aarhus, Denmark"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6082-3418","authenticated-orcid":false,"given":"Salahuddin","family":"Khan","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, College of Engineering, King Saud University, Riyadh 11421, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8263-1572","authenticated-orcid":false,"given":"Mohammad","family":"Alibakhshikenari","sequence":"additional","affiliation":[{"name":"Department of Signal Theory and Communications, Universidad Carlos III de Madrid, 28911 Legan\u00e9s, Spain"}]},{"given":"Ali","family":"Lalbakhsh","sequence":"additional","affiliation":[{"name":"School of Engineering, Macquarie University, Macquarie Park, NSW 2109, Australia"}]},{"given":"Muhammad Abbas","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Balochistan University of Information Technology, Engineering and Management Sciences, Quetta 87300, Pakistan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2972-9965","authenticated-orcid":false,"given":"Raed A.","family":"Abd-Alhameed","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Informatics, University of Bradford, Bradford BD7 1DP, UK"},{"name":"Information and Communication Engineering Department, College of Science and Technology, Basrah University, Basra 61004, Iraq"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4668-7461","authenticated-orcid":false,"given":"Ernesto","family":"Limiti","sequence":"additional","affiliation":[{"name":"Electronic Engineering Department, University of Rome \u201cTor Vergata\u201d, Vial Del Politecnico 1, 00133 Rome, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Kiani, S.H., Altaf, A., Abdullah, M., Muhammad, F., Shoaib, N., Anjum, M.R., Dama\u0161evi\u02c7cius, R., and Bla\u017eauskas, T.
