To achieve the dual-band characteristics, two adjunct partial arc-shaped small slots are joined to two main circular slots embedded in the ground of the antenna structure. With a reduced size of 30 \u00d7 28.5 \u00d7 0.8 mm3, the proposed antenna presents a dual-band characteristic. The design is optimized using a High Frequency Structure Simulator (HFSS) followed by experimental verifications. An impedance bandwidth, for S11 \u2264 10 dB, that covers the 1.8 GHz and 2.4 GHz bands is accomplished, which makes the proposed antenna basically suitable for hand-held devices and medical applications. More applications such as digital communication system (DCS) 1.71\u20131.88 GHz, personal communication services (PCS) 1.85\u20131.99 GHz, Universal and mobile telecommunications system UMTS 1.92\u20132.17 GHz, Bluetooth 2.4\u20132.5 GHz, and Wi-Fi 2.4\u20132.454 GHz, Industrial Scientific and Medical radio frequency (RF) band ISM-2.4 GHz, Wireless Local Area Network (WLAN-2.4) are possible by simply changing one of the geometrical antenna dimensions. The antenna is characterized by stable radiation patterns as well.<\/jats:p>","DOI":"10.3390\/electronics8101123","type":"journal-article","created":{"date-parts":[[2019,10,7]],"date-time":"2019-10-07T03:34:01Z","timestamp":1570419241000},"page":"1123","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["A Compact Semi-Circular and Arc-Shaped Slot Antenna for Heterogeneous RF Front-Ends"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8179-4062","authenticated-orcid":false,"given":"Chemseddine","family":"Zebiri","sequence":"first","affiliation":[{"name":"Department of Electronics, University of Ferhat Abbas, S\u00e9tif 1, S\u00e9tif 19000, Algeria"},{"name":"School of Electrical Engineering and Computer Science, University of Bradford, Bradford BD71DP, UK"}]},{"given":"Djamel","family":"Sayad","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, University of 20 Aout 1955\u2014Skikda, Skikda 21000, Algeria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0440-8025","authenticated-orcid":false,"given":"Issa","family":"Elfergani","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8312-7087","authenticated-orcid":false,"given":"Amjad","family":"Iqbal","sequence":"additional","affiliation":[{"name":"Centre for Wireless Technology, Faculty of Engineering, Multimedia University, Cyberjaya 63100, Malaysia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2972-9965","authenticated-orcid":false,"given":"Widad F.A.","family":"Mshwat","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Computer Science, University of Bradford, Bradford BD71DP, UK"}]},{"given":"Jamal","family":"Kosha","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Computer Science, University of Bradford, Bradford BD71DP, UK"}]},{"given":"Jonathan","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2972-9965","authenticated-orcid":false,"given":"Raed","family":"Abd-Alhameed","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Computer Science, University of Bradford, Bradford BD71DP, UK"},{"name":"Information and Communication Engineering Department, Basrah University College of Science and Technology, Basrah 24001, Iraq"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1109\/TAP.2015.2503732","article-title":"Planar ultrawideband antennas with improved realized gain performance","volume":"64","author":"Tang","year":"2015","journal-title":"IEEE Trans.
