A miniature Multiple Input Output (MIMO) Ultrawideband (UWB) antenna with C-band notch is recommended for wireless communications. The radiator etched on an economical FR4 substrate and 40 × 21 mm2 in size. comprised of a circularly notched rectangular patch embedded ellipse fed by 50-Ω microstrip line. To reduce mutual coupling < −18 dB throughout the whole operational bandwidth 2.94–11.61 GHz without employing any device, two radiators are positioned side-by-side separation 0.03 λ0 (λ0...
This paper presents a compact minkowski patch antenna for raising return loss as well reducing mutual coupling MIMO systems. A major limiting factor of systems is which arises mainly due to the smaller spacing between multiple antennas. Mutual one parameter diminish channel capacity describe inclusive presentation system. Hence proposed system resonates at first resonant 2.5 GHz, second resonate 3.5 third 5.2 GHz and finally 7.0 observed that an improvement in bandwidth reduction have 54 dB,...
