The antenna proposed herein, possesses two mutually orthogonal staircase-etched radiators for achieving a wide bandwidth. The radiating elements are placed mutually perpendicular in order to achieve polarization diversity and high isolation, i.e. for minimization of mutual coupling effect between adjacent radiating elements. The antenna exhibits an extremely wide frequency bandwidth covering 1.2\u201319.4 GHz except two frequency band notches centered at 3.5 and 5.5 GHz, respectively, originated due to the incorporation of a \u201cRectangular Complementary Split Ring Resonator (RCSRR)\u201d structure and by etching dual \u201c<jats:italic>L<\/jats:italic>-shaped\u201d slits in the ground plane. The center frequency of the notched bands is adjusted by fine tuning of the dimensions of the incorporated band-notching structures. Isolation level (<jats:italic>S<\/jats:italic><jats:sub>21<\/jats:sub>) better than \u221220 dB has been obtained due to the insertion of a \u201c<jats:italic>T<\/jats:italic>-shaped\u201d parasitic element as a decoupling structure.

Obtained results show that the miniaturized MIMO diversity antenna is undoubtedly a capable contender for communications supporting an extremely wide impedance bandwidth along with band-notched features for WLAN and WiMAX.<\/jats:p>","DOI":"10.1017\/s1759078719000266","type":"journal-article","created":{"date-parts":[[2019,3,19]],"date-time":"2019-03-19T08:29:32Z","timestamp":1552984172000},"page":"719-728","source":"Crossref","is-referenced-by-count":16,"title":["Low-profile, extremely wideband, dual-band-notched MIMO antenna for UWB applications"],"prefix":"10.1017","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2350-1687","authenticated-orcid":false,"given":"Ankan","family":"Bhattacharya","sequence":"first","affiliation":[]},{"given":"Bappadittya","family":"Roy","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0297-7870","authenticated-orcid":false,"given":"Rafael F.
