“…However, at the mobile terminal symmetries may not always be exploited since the antenna shape is usually predetermined, as described above. Furthermore, accommodating [10] consisting of 11×11 four-port antenna elements (see insets) based on a square geometry with feed networks using power dividers and hybrid couplers realized in stripline technology. a feed network for simultaneously driving distributed coupling elements may not be feasible due to spatial restrictions (cf.…”

“…[9]). If the port potential is not fully exploited, the feed network becomes less complex and the antenna size can be further reduced, as shown in [10], where a complete prototype of a multimode massive MIMO array consisting of fourport antenna elements based on a square plate is presented (Fig. 2).…”

While on the one hand 5G and B5G networks are challenged by ultra-high data rates in wideband applications like 100+ Gbps wireless Internet access, on the other hand they are expected to support reliable low-latency Internet of Things (IoT) applications with ultra-high connectivity. These conflicting challenges are addressed in a system proposal dealing with both extremes. In contrast to most recent publications, focus is on the frequency domain below 10 GHz. Towards this goal, multi-mode antenna technology is used and different realizations, offering up to eight uncorrelated ports per radiator element, are studied. Possible baseband architectures tailored to multi-mode antennas are discussed, enabling different options regarding precoding and beamforming.

“…To support this trend there is a great and increasing number of MIMO antenna designs, many of which are incorporated into a small volume [1][2][3][4]. Such antennas need to be characterized with respect to their performance within MIMO systems and considering often complex interactions between multiple antenna ports.…”

Abstract-This paper proposes an improved technique to calculate the Envelope Correlation Coefficient (ECC) by directly using the spherical mode spectrum of the antenna under test. The technique avoids errors due to numerical pattern integration and simplifies post-processing for nearfield measurements. The technique is successfully tested on two different antenna types, in the total number of four MIMO configurations.Index Terms-MIMO, envelope correlation coefficient, spherical near field, antenna measurement.

“…In order to adapt to this tendency, many novel techniques are developed in the past few decades. Among which, ultra-wide band (UWB) technique and multiple input multiple output (MIMO) concept have aroused wide interest in both academia and industry [1][2] . Hence, as one of the most important component in the new generation wireless communication system, the UWB antenna and the MIMO antenna have evolved so quickly and become one of the hottest field in the forefront of antenna design.…”

Abstract-In this paper, the band-notched characteristic inheritance in ultra-wide band (UWB) multiple input multiple output (MIMO) antenna array design is studied. First, the structure parameters and return loss of a monopole antenna are optimized to obtain desired UWB property. Then, the bandnotched characteristic is realized in 7.9-8.4GHz by using the rectangle split ring resonator (r-SRR). Furthermore, this UWB antenna is utilized to form a MIMO antenna array based on quasi-self-complementary antenna technique. Finally, the simulation results show that on the one hand, the band-notched property of the unit antenna can be inherited by the antenna array; on the other hand, the bandwidth of the stop band for antenna array is increased by about 66% compared with that of the antenna unit.
