Dual-band multiple-element MIMO antenna system for next-generation smartphones
Kiani, Saad Hassan; Marey, Mohamed; Savcı, Hüseyin Şerif; Mostafa, Hala; Rafique, Umair; Khan, Muhammad Amir (MDPI (Multidisipliner Digital Publishing Institute), 2022)This work presents a cost-effective multiple-element multiple-input multiple-output (MIMO) antenna system for next-generation smartphones. The proposed antenna system is developed on a 0.8 mm thin FR-4 substrate with a ... -
Eight element dual-band MIMO array antenna for modern fifth generation mobile phones
Abubakar, Hassan Sani; Zhao, Zhiqin; Kiani, Saad Hassan; Rafique, Umair; Alabdulkreem, Eatedal; Elmannai, Hela (Elsevier GmbH, 2024)In this paper, an eight-element multiple-input multiple-output (MIMO) antenna with dual-band response is designed for fifth-generation (5G) mobile devices. The proposed MIMO systems’ radiators are placed in the inner side ... -
Performance enhancement of Vivaldi-shaped planar UWB antenna using a single-layer FSS reflector
Kiani, Saad Hassan; Rafique, Umair; Savcı, Hüseyin Şerif; Rmili, Hatem; Parchin, Naser Ojaroudi; Algarni, Abeer D.; Elmannai, Hela (2024)This work proposes the design of a frequency-selective surface (FSS)-based planar monopole antenna for ultra-wideband (UWB) communication applications. The UWB response is observed by integrating a Vivaldi-shaped slot and ... -
Side-edge dual-band MIMO antenna system for 5G cellular devices
Kiani, Saad Hassan; İbrahim, İmran Mohd; Savcı, Hüseyin Şerif; Rafique, Umair; Alsunaydih, Fahad N.; Alsaleem, Fahd; Alhassoon, Khaled; Mostafa, Hala (Elsevier GmbH, 2024)An eight-element multiple-input multiple-output (MIMO) antenna system is presented for two distinct 5G allocated bands, i.e., 3.5 and 5.2 GHz. The MIMO radiating elements are printed on each side of the mobile phone chassis, ... -
