“…5(b), which is calculated using the measured and simulated S-Parameters. The results shows that the measured envelope correlation (dotted line) is reasonably matched with the simulated results (solid black line) under the 0.25 reference level, which is much better than the criteria of correlation coefficient less than 0.7 for base station antennas [15]. Further, the channel correlation has also been calculated for the MIMO evaluation using the measurement data in the reverberation chamber along with the MATLAB code and is shown in Fig.…”

A novel antenna with both horizontal and vertical polarizations is proposed for 1.7-2.1 GHz LTE band small cell base stations. Horizontal polarization is achieved by using the vivaldi antennas at the main PCB board in azimuth plane. Whereas, the vertical polarization is obtained using the rectangular monopole with curved corners in proximity of the horizontal elements. A prototype antenna associated with 8-elements (four horizontal and four vertical) is fabricated on the FR4 substrate with the thickness of 0.2 cm and 0.12 cm for vivaldi and monopole antennas, respectively. Experimental results have validated the design procedure of the antenna with a volume of 14 x 14 x 4.5 cm 3 and indicated the realization of the requirements for the small cell base station applications.

The present technology fulfills the requirement of high data rate and high channel capacity using multiple input multiple output (MIMO) technology. The MIMO capacity of the system is increased linearly but due to the multiple antennas placed near to each other, problem of mutual coupling exists, which degrades the maximum achievable performance of the system. The problems of multipath propagation can be solved using MIMO system. The isolation improvement methods decrease the mutual coupling among antenna elements, and improve the gain and efficiency of the system. In this paper, decoupling network isolation approach, parasitic element approach, defected ground structure, Neutralization line, isolation improvement based on metamaterials, isolation improvement using PIN diode, varactor diode, and feeding structure have been incorporated, and their merits and demerits have been discussed. The effect of different permittivity material on antenna parameters has also included.

“…WLAN and WiMax bands were achieved by using slotted ground structure and metamaterial rectangular split ring resonator. Many MIMO antennas have been proposed to reduce the mutual coupling for UWB systems [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In [4][5][6][7][8], various decoupling structures have been inserted between two antenna elements to enhance wide band isolation.…”

Abstract-In this paper, a compact multiple-input-multiple-output (MIMO) antenna is proposed for ultra wideband (UWB) communication. The UWB MIMO antenna consists of two identical monopole antenna elements with a comb-line structure on the ground plane to improve impedance matching and enhance isolation. Simulation and measurement have been analysed in terms of reflection coefficient, mutual coupling, dispersion diagram, radiation pattern, peak gain, efficiency and envelope correlation coefficient. Results show that the antenna has an impedance bandwidth larger than 3.1-10.6 GHz, mutual coupling between the two ports lower than −25 dB and envelope correlation coefficient less than 0.001 across the UWB band. The proposed antenna has a compact size of 26 × 31 mm 2 . All the measured and calculated results show that the proposed UWB MIMO antenna is a good candidate for UWB MIMO systems.
