“…The metrics used to evaluate the diversity performance of the tri-band antennas are: mean effective gain (MEG) [6], envelope correlation coefficient [7], diversity gain (DG) for selection combining at 1% probability [8][9] and diversity system gain (DSG) [10] or equivalently, effective diversity gain [11]. The metrics are calculated in Matlab using formulas from [6][7][8][9][10] and 3D far field antenna gain patterns from simulations and measurements, under the assumption of uniform 3D propagation model.…”

“…Thereby, its signal to noise ratio (SNR) is of a very low magnitude, the system performance deteriorated, and its development restrained. Meanwhile, without sacrificing transmitted power, multiple-input multipleoutput (MIMO) technology has attracted major interest for its abilities to enhance the data rate and reliability in rich scattering environments [1]. Therefore, UWB MIMO technology is a rising research field to solve the multi-path fading and low SNR problems of UWB system [2] in recent years, and selective fading problem of MIMO system can also be improved by it.…”

Abstract-A compact dual band-notched ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna with uniform rejection performance is designed on an FR4 substrate (35 × 23 × 1.6 mm 3 ). Compared with the existing UWB MIMO antennas, a second-order notched band with uniform performance for 5.15-5.825 GHz is achieved, which results from the interplay between a 1/3λ open-end slot and a 1/2λ parasitic strip. A 1/4λ open-end slot is also applied to the 3.3-3.7 GHz reject band. The two slots are connected at their open ends, that can help to get the uniform reject performance for 5.15-5.825 GHz and make the high cutoff frequency of the impedance matching band go toward the higher frequencies. Excluding the two rejected bands, a band with |S 11 | ≤ −10 dB, |S 21 | ≤ −17 dB and frequency ranged from 3.1 to 10.9 GHz is achieved, and results show that a uniform performance for 5.15-5.825 GHz is obtained.

“…Multipath fading is a serious problem especially in urban and suburban environment which will degrade the system performance. The use of multiple-inputmultiple-output (MIMO) technology is an effective way to improve the date rate and increase the channel capacity without sacrificing additional spectrum or transmitted power in a rich scattering environment [1][2][3][4][5]. Low mutual coupling between different ports of the multiple antennas is a pivotal to realize good performance of a MIMO system.…”

Abstract-A compact dual-band multiple-input-multiple-output (MIMO)/diversity antenna is proposed. This antenna is designed for 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5 GHz WiMAX applications in portable mobile devices. It consists of two back-to-back monopole antennas connected with a T-shaped stub, where two rectangular slots are cut from the ground, which significantly reduces the mutual coupling between the two ports at the lower frequency band. The volume of this antenna is 40 mm * 30 mm * 1 mm including the ground plane. Measured results show the isolation is better than −20 dB at the lower frequency band from 2.39 to 3.75 GHz and −25 dB at the higher frequency band from 5.03 to 7 GHz, respectively. Moreover, acceptable radiation patterns, antenna gain, and envelope correlation coefficient are obtained. These characteristics indicate that the proposed antenna is suitable for some portable MIMO/diversity equipments.
