Eight-Port MIMO_8-P Antenna Printed on Flexible-Substrate for Multiple-Wireless Applications in WLAN-mmWave

A dual-band single-port and eight-port MIMO8-P antenna printed on flexible-Rogers substrate is discussed. The single as well as eight-port antenna occupies space of 400 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and 10401 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>. The radiating-patch comprises of half-modified circular-patch with rectangular-slotted ground and embedded rectangular strip. The antenna produces two wide-bands in both the configuration with eight-port MIMO bandwidth corresponds to Band1=3.88GHz-7.14GHz and Band2=10.15GHz-40.0GHz respectively. The eight-port configuration maintains isolation of more than 20.0dB in both the operating bands with averaged diversity-performance corresponding to ECC<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8-P</inf> =2×10-4 (Band1) and 12×10-4 (Band2), DG<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8-P</inf> ≅ 10.0dB, TARC<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8-P</inf> =-10.0dB and -12.0dB in both the bands with CCL<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8-P</inf> =0.10 and 0.08 b/s/Hz in Band1 and Band2. The antenna also offers peak-realized-gain of more than 3.0dB with desired radiation patterns in 2-D orthogonal planes.
