A Slotted Compact Four-port Truncated Ground Structured MIMO antenna for Sub-6 3.4 GHz 5G Application

Abstract

A novel high performance four-port multiple input multiple output antenna is suggested for 5G application functioning at 3.4 GHz band. The antenna design measures an inclusive volume of 32 mm × 32 mm × 0.8 mm 3 . The broad frequency bandwidth, excellent gain, decreased interelement gap, and effective isolation within the MIMO components of the proposed system are clearly novel. Each antenna in the four-element MIMO system has been situated orthogonally to the others while maintaining a small size and good result. The antenna has exceptional average total efficiency in the 5G sub-6 GHz spectrum and is in good agreement with the measured results. It also offers a high realized gain compared to prior MIMO antennas. The antenna has a high impedance matching whose isolation is about −28 dB, computed envelope correlation coefficient smaller than 0.10, channel capacity loss average value less than 0.2 bits per second per hertz, and the diversity gain about 10 dB. The typical peak realized antenna gain of the offered MIMO antenna is also delivered with a high radiation efficiency at the frequency of 3.4 GHz. The reflection coefficient, mutual coupling, radiation pattern, current distribution, and gain of antennas are all measured and explained. The design has a compact high volume and adequate bandwidth with good accomplished gain making the antenna very strong for 5G application.

Compact Wideband Four Elements MIMO Antenna for 5G Applications

“…Four elements MIMO antennas have been proposed for wireless applications and 5G technology [9][10][11][12][13][14][15][16]. A square-shaped four elements MIMO antenna with offset feedline and defected ground structure (DGS) is designed [9].…”

“…The elements are configured in plus shape on isolated ground to obtain isolation > 20 dB [11]. A P-shaped antenna with partial ground for 5G applications offers isolation > 28 dB [12]. Octagonshaped [13] and CPW feed [14] UWB MIMO antennas have been reported; however, these structures have large size.…”

“…The novel structure employs neither any isolation techniques nor any meta-material or split ring resonator (SRR) yet offers high isolation. It is simple to design and have smaller dimensions than the reported structures [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The offset fed antenna structure is designed from a rectangular and semicircular monopole antenna.…”
