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.

“…a lower band (including LTE700, LTE800, and GSM), and a upper band (including DCS, PHS, PCS, UMTS, Bluetooth, and WLAN). It should be reemphasized that the present design allows an easier implementation of an octo-band operation antenna than those using an additional patch [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…Recently, the band of Long Term Evolution (LTE) has attracted much attention, because it is promising in the 4G communication due to larger amount and higher speed of transmission. Therefore, there has been much research focusing on the application of LTE operation on smart phones, laptop computers, and tablet computers [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, it is difficult to design an antenna for the LTE700 band using conventional dipole or monopole antennas, since the low frequency operation leads to a longer current path.…”

Abstract-An LTE smart mobile antenna with multiband operation is proposed to work in the bands of LTE, GSM, DCS, PCS, PHS, UMTS, Bluetooth, and WLAN. Compared with those reported in the literature, the proposed antenna features a simple and straightforward design procedure, which is composed of three easy steps. Firstly, A three-dimensional meandering monopole antenna is constructed along the edge of a rectangular PCB to act as the main radiator, resulting in the bands of LTE, DCS, and PCS, PHS, and UMTS. Secondly, a shorted stub is fabricated to excite the GSM band, and also to improve the impedance matching in the bands of LTE and GSM. Finally, the second shorted stub is added to radiate in the band of WLAN. The numerical results show that the −6 dB return-loss bandwidths are from 0.7 GHz to 0.985 GHz (0.285 GHz, 34%) in the lower band and from 1.64 GHz to 2.535 GHz (0.895 GHz, 43%) in the higher band. The corresponding measured data are from 0.7 GHz to 1.03 GHz (0.33 GHz, 38%) in the lower band and from 1.64 GHz to 2.55 GHz (0.91 GHz, 43%) in the higher band. The measured antenna gains are about 2 to 3 dBi in the lower and higher bands, respectively.

“…Recent multi-element handset antenna designs can be found in, e.g., [7][8][9][10]. The design presented in [7] implements a four-element MIMO antenna for the low band (LB) (698-960 MHz), but the study does not consider high band (HB) MIMO.…”

Abstract-This paper proposes a two-element LTE MIMO handset antenna with physically different main and diversity antennas. The performance of the design is studied theoretically and experimentally. The investigated design utilises physically different main and diversity antennas to improve especially the low-band MIMO performance. A Combined Parasitic-coupled, Aperture-Matched (CPAM) antenna is used as the main antenna, and the diversity antenna is a simple Capacitive Coupling Element (CCE) design. The antenna covers the LTE bands from 698-960 MHz and 1710-2690 MHz with fixed matching circuits suitable for low-band (LB) Carrier Aggregation (CA). Measured total efficiency of the antennas is from −3 to −6 dB and −2 to −5 dB at the low and high bands, respectively. In the MIMO case, envelope correlation coefficient (ECC) and multiplexing efficiency (η mux ) are studied also from measurements.
