Design and Analysis of Enhancing Impedance Bandwidth and high Isolation Characteristics of UWB MIMO Antennas
Keywords:
Compact, MIMO, band notch characteristics for mutual coupling, and UWB antennaAbstract
A small dual band-notched two port multiple input and multiple output antenna with low mutual coupling for ultra-wide band systems is the subject of this planned research study. The two identical monopole elements are fed by two 50Ω coplanar waveguide lines, making the total antenna dimensions of 18 X 29.5 X 1.6 mm³. Manufactured side by side on the upper surface of FR-4 ground plane substrates.A T-shaped stub was substituted for the rectangular stub in order to lessen the mutual coupling between the parts. The suggested antenna covers the UWB spectrum and records a wide resistance bandwidth at each port between 2.3 and 12GHz. This antenna has a modest size and design. The element's mutual coupling is less than -20 dB. Efficiency is 85% and the envelope correlation coefficient is less than 0.04. Evaluation of antenna parameters is done in terms of return loss, gain, DC, and ECC.
