“…Four-port MIMO antenna with bandwidth 24.55GHz-26.50GHz is designed for a 24.0GHz center frequency mm-Wave band and the gain is achieved by using a 9×6 circular Split Ring (CSR) [15]. A low-frequency 5G-NR band with four-port accommodates n77, n78, and n79 bands [16], [17], [18], [19]. A super wideband antenna with four notched bands offers operational bandwidth of 1.15GHz-40.0GHz and maintains isolation by arranging the truncated elliptical self-complimentary patch in an orthogonal fashion [20].…”

In this endeavor, miniaturized quad-port MIMOMB (multiple-input-multiple-output multiband) antenna with an overall area of 400 mm 2 offering wider-impedance-bandwidth of 8.31GHz-36.14GHz is reported which covers multiple bands including X-band (8.00-12.0 GHz), Ku-band (12.0-18.0 GHz), Kband (18.0-27.0 GHz), partial GHz) is reported for wideband infrastructure. The proposed antenna radiating EM energy is printed on very thin Rogers RTDuroid5880 substrate with thickness 0.254mm. The radiating EM wave patch consists of hexagonal geometry which is etched with a circular-rectangular slot and partialground etched by a beveled shape patch for matching of impedance. The conformal capability of the proposed antenna is verified by S-for single-port, dual-port, and proposed four-port antenna. The time-domain analysis confirms the faithful reception of transmitted signals in far-field regions. The diversity performance including ECCMB, DGMB, TARCMB, CCLMB, and MEGMB is below permissible standard values with a maximum peak gain of 7.17dBi with stable 2-D radiation patterns in principal planes. The Specific-Absorption-RateMB (SAR) analysis is carried out at different operating frequencies in Microwave-Millimeter wave bands with SAR ≤1.60W/Kg in human phantom tissue and makes it suitable for on-body wireless applications.
