A novel approach for low mutual coupling and ultra-compact Two Port MIMO antenna development for UWB wireless application

A tapered feed UWB-MIMO antenna with high characteristics based on fractal method

“…The conventional ultra-wideband planar antennas listed in table 2 that have been reviewed in the literature are contrasted with the novel MIMO monopole antenna. The comparison table demonstrates that the modern 1 × 2 array antenna has a smaller electrical size than the MIMO antennas covered in more recent researches [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Additionally, the dual diversity parallel planar antenna proposals a higher gain of 5.96dBi at the operational frequency of 11.98 GHz, a small value of ECC, and a good isolation outcomes in comparison to all references.…”

“…Mutual coupling, which happens when the antenna parts interact electromagnetically, is a critical component of the MIMO antenna design [20]. With the exception of [22] and [23], the reported works [21][22][23][24][25] have a decent isolation value when considered separately, but the antennas' overall size is a little bit big. The antenna will be unsuitable for a compact application by using an additional part for the size of the device.…”

Mutual Coupling Reduction in Dual-Band MIMO Antenna Using Parasitic Dollar-Shaped Structure for Modern Wireless Communication

“…Various techniques have been proposed to increase the isolation between two monopole radiators, including metamaterial [1], defected ground [3], EBG structure [4], combshaped structure [9], polarization diversity [12], and slotted ground structure [19]. For the antenna of this paper, a novel dollar-sign-shaped PDSS is employed as an isolating element between the monopole radiators (within the 0.04λ gap), as depicted in Figure 9b.…”

“…In light of these challenges, several MIMO antennas aiming to reduce mutual coupling among closely-deployed antenna radiators for wireless applications are suggested in [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], and [17]. The Ultra-wideband (UWB) antennas in [1] and [2] operating in the 4-12 GHz and 2.95-15.65 GHz bands, respectively, achieved high isolation using Quad G-shaped metamaterial and a parallel strip resonator. However, UWB technology is nearly obsolete today due to issues of co-existence and interference with other wireless technologies.…”

Self-decoupled tri band MIMO antenna operating over ISM, WLAN and C-band for 5G applications

“…In the literature, various works have already been presented where some MIMO antennas are loaded with parasitic patches or DGS ground planes [ [13] , [14] , [15] , [16] , [17] , [18] , [19] ] and many others are self-decoupled [ [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] ].
