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 ...
Ultra-wideband pentagonal fractal antenna with stable radiation characteristics for microwave imaging applications

Khan, Muhammad Abbas; Rafique, Umair; Savcı, Hüseyin Şerif; Nordin, Anis Nurashikin; Kiani, Saad Hassan; Abbas, Syed Muzahir (MDPI, 2022)

For microwave imaging applications, a design for an ultra-wideband (UWB) fractal antenna is presented. The antenna design is composed of a pentagonal fractal patch radiator fed by a modified co-planar waveguide (CPW) ground ...
