“…To make the MIMO system work normally, it is necessary to reduce the correlation of the antenna elements in the system [1]. For this reason, several methods for reducing the correlation between elements in an antenna array in a MIMO system have been proposed, for example, defect ground structure decoupling [2,3], parasitic stub decoupling [4][5][6], neutralization line decoupling [7][8][9], diversity technology decoupling [10][11][12], and electromagnetic band-gap (EBG) structure decoupling [13,14].…”

A miniaturized ultra-wideband multiple-input multiple-output (UWB MIMO) two-port antenna with high isolation based on FR4 is designed in this article. The size of the antenna is only 18 × 28 × 1.6 mm3. The MIMO antenna consists of two identical antenna elements symmetrically placed on the same dielectric substrate in opposite directions. By loading three crossed X-shaped stubs between two unconnected ground planes, high isolation and good impedance matching are achieved. The working frequency band measured by this UWB MIMO antenna is 1.9–14 GHz, and the isolation is kept above 20.2 dB in the whole analysis frequency band. Good radiation characteristics as well as envelope correlation coefficient (ECC, <0.09), mean effective gain (MEG), and channel capacity loss (CCL) in the passband meet the requirements of the application, which can be applied to the UWB wireless communication system. To verify the applicability of the proposed method for enhancing the isolation between antenna elements, the two-port antenna structure was extended to a four-port antenna structure. In the case of loading the X-shaped stubs to connect to the ground plane, the isolation of the antenna is maintained above 15.5 dB within 1.7–14 GHz.

“…To overcome the problem of mutual coupling, different decoupling structures are designed in [7][8][9][10]. UWB system also has some electromagnetic interference with coexisting narrow bands, thus different notch structures are presented to stop this interference [11][12][13][14][15][16][17][18][19][20][21][22][23].…”

A compact pot-shaped Multiple Input Multiple Output (MIMO) Antenna with triple notched band characteristics is presented for Ultra Wide Band (UWB) applications. The comprehensive dimension of the presented antenna is 17 × 32 mm 2 . The presented antenna has two identical potshaped radiators, 7-shaped stubs, T-shaped strips, M-and C-shaped slots. Two novel 7-shaped stubs are connected to the antenna ground plane to obtain −22 dB enhanced isolation. The presented antenna works from 2.95 to 12.1 GHz with triple stopped WiMAX, WLAN, and X bands. A novel T-shaped strip is connected to the antenna ground plane to stop the WiMAX band (3.3-4.4) GHz. C-and M-shaped slots are etched in the antenna radiators to stop WLAN (5.20-6.12) GHz and X (7.6-8.15) GHz bands, respectively. The peak gain of the proposed antenna is from 1.5 to 5 dB with a radiation efficiency of 80-90%. The Envelope Correlation Coefficient (ECC) of the proposed antenna is less than 0.01 with a Diversity Gain greater than 9.99 except for the notched bands.
