Abstract
Multi-element Ultra-Wideband (UWB) antennas with multi-input multiple-output (MIMO) capability are available. Mutual coupling between antenna elements is considerably reduced since this antenna created utilizing contemporary symmetrical shape, orthogonal arrangement technology. In addition, antenna sizes are efficiently miniaturized by applying two sides of symmetric configuration, partial and faulty ground structure, to increase their bandwidth of impedance, they used a decoupling structure in addition to multi-slot and multi-slit systems. The antenna has a low-profile design with a tiny size 40 mm × 47 mm ×1.6 mm. In addition, by combining varied form slots and slits on the circular radiating elements and the decoupling structure, the suggested antenna provides four notched band characteristics. This antenna has a larger bandwidth of (2-11) GHz. In addition, this antenna also has low mutual coupling (<-15dB), (Multiplexing Efficiency<-5.0dB), low envelope correlation coefficient (ECC<0.06, excepting the four notched bands), constant gain, and radiation patterns quasi-omnidirectional throughout the bandwidth impedance. A good output exchange is therefore obtained for the antenna. This antenna might be used in UWB-MIMO wireless communication systems, including portable UWB-MIMO systems.
