摘要：
This paper presents design of a 4-element crescent-shaped two-sided multiple-input-multiple-output (MIMO) antenna, employing pattern and polarization diversity with improved element-to-element isolation, for UWB, X and Ku band wireless applications. The proposed crescent-shaped MIMO structure consists of two antennas on the top and remaining two antennas on the bottom sides of the substrate. The developed antenna operates in a frequency range from 2.8 to 15.2 GHz, covering the entire UWB 3.1–10.6 GHz, X-band and portion of Ku-band giving element-to-element isolation of more than 20 dB in most of the operating bands. Also, the proposed MIMO structure gives a maximum gain of 6.6 dBi with radiation efficiency from 75 to 95% in the operating band. The important MIMO parameters like envelope correlation coefficient (ECC < 0.005), channel capacity loss (CCL < 0.03 bits/s/Hz), mean effective gain (MEG < − 3 dB) and total active reflection coefficient (TARC < − 10 dB) are presented to estimate the performance of the developed UWB MIMO system.
