A Different Shaped Radiating Element Wide Band Multi-Band Massive MIMO Antenna for 5G/WLAN applications with Enhanced Correlation Coefficient

Abstract

In this paper, a different shaped 8-element multiband multiple input multiple output (MIMO) massive antenna is investigated for 5G and various applications. It can be operated on various wireless communication application such as WLAN (5.15GHz to 5.30GHz and 5.73GHz to 5.85GHs) and 5G band & C-band (4 to 8GHz) for satellite communication with wideband. The 8-element Massive MIMO antenna is designed for 6GHz. This antenna is working on multiband with wideband bandwidth. The defected ground structure (DGS) systems are used for enhancement of return loss, isolation, total active reflection coefficients (TARC), correlation coefficients (CC) and envelope correlation coefficients (ECC). The rectangular shaped DGS is used in the ground plane for improvement of various parameter of antenna. This antenna provides return loss (RL) and isolation is less than -10dB.

Development of a Wide Bandwidth Massive Eight Dissimilar Radiating Element Multiband MIMO Antenna for mm-Wave Application

“…Figure 15 shows the antenna radiation pattern. TARC is less than 0.16, CC is less than 0.0122, ECC is less than 0.00015, and DG is near to 9.9985 [20].…”

“…The antenna element bandwidth [18][19][20] between the remaining elements of patch-2 are shown in Figure 7. It operates on the 5.7GHz, with less than -24.79dB return loss (S 22 (m 1 )), less than -11dB isolation (S 26 (m 2 )), and 437.3MHz (7.289%) bandwidth.…”

“…The antenna's geometrical structure, i.e. length L re and width W re , was created using the square radiating patch transmission line model [20], which has the dimensions listed in Table I, which shows the measurements of 8 radiating elements with varying cut slots. A rectangular cut slot [20] is placed in patch-1 and patch-3, with length C and width D. A similar rectangular cut slot [20] is placed in patches-5, -7, and -8.…”
