“…The increasing demand for higher data throughput and the need for more reliable connections has motivated the use of multiple antenna techniques, which is a key feature for increasing the performance of wireless communication systems. In order to improve high data rates and secrecy, multiple antennas can be applied with spatial multiplexing, moreover, channel capacity can be greatly increased without sacrificing the spectrum of frequency and transmit power [1][2][3][4]. Multiple-input-multiple output (MIMO) antennas should have multiple ports and it is expedient to have those ports isolated and well matched as no matching network is connected.…”

Characteristic Mode Analysis and Design of Wide Band MIMO Antenna Consisting of Metamaterial Unit Cell

This paper presents a full wave simulation and characteristic mode-based design of a multiple-input-multiple-output (MIMO) antenna at 5.8 GHz for wireless local area network applications. The driven analysis comprises two antennas that are placed orthogonal to each other. A metamaterial unit structure in the form of a rectangular loop resonator is placed around the antenna element to reduce the electromagnetic interference and to increase the isolation between the two monopoles. A characteristic mode technique is employed to find out the dominant mode of the proposed antenna without a feeding port. It was revealed that mode 1 was the dominant mode among the three modes used. The MIMO antenna is constructed and measured using a vector network analyzer. A good isolation of less than 25 dB was attained with a wide impedance bandwidth of 65.5%.

In this research work, a modified shared rectangular radiator is proposed for 5.7-GHz wireless application using multiple cuts and partially stepped ground. The shared design requires no isolating structure to decouple the ports. The proposed shared geometry produces >13 dB isolation in the 4.4-to 6.4-GHz operating band. The gain varies from 3.0 to 6.2 dBi, and radiation efficiency is >70 % in the band. The mutual coupling among the port is reduced by orthogonal arrangement of ports, and envelope correlation coefficient (ECC) is <0.04 in the presented band. Apart from this, isolation in the proposed shared radiator is enhanced by additional multiple cuts with stepped ground. The indooroutdoor suitability of multiple input multiple output (MIMO) antenna for isotropic and Gaussian medium is checked by mean effective gain (MEG) and specific absorption rate (SAR). The presented results of MEG and SAR fulfill the required safety norms as per the ITU for different environments. K E Y W O R D SECC, MEG, MIMO antenna, isolation, SAR, TARC

“…For UWB-MIMO system, how to maintain acceptable isolation (no less than 10 dB) between antenna elements through the wide operational band is a challenging task. Many researches has been reported recently [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Twoelement MIMO antenna system is reported in [5], without using common ground and separate the two elements about 0.37 0 from each other, no less than 15 dB isolation can be realized.…”

“…Polarization diversity is also an effective way in obtaining lower mutual coupling between antenna elements. In [10][11][12][13][14][15][16][17][18], antenna elements are placed perpendicular to each other to exploit polarization diversity and achieve high isolation. While in [19], polarization diversity between leaf-shaped slot antenna and similar shaped monopole is used to obtain good isolation in UWB high band (7.25-10.25 GHz).…”

A four element multiple input multiple output (MIMO) antenna system for UWB applications is presented. The system consists of two identical slot dipoles and two identical planar monopoles. Polarization diversity between different kinds of antennas can realize lower coupling between antenna elements, and by using a couple of inverted L-shaped stubs and an inverted Z-shaped stub as decoupling structures, isolation can be further improved. For both simulation and measurement, higher than 17 dB isolation between antenna elements can be obtained through the whole UWB band (3.1-10.6 GHz). The envelope correlation coefficient, antenna gain, efficiency and other performances are also provided.
