Summary: This paper proposes a 12-port MIMO antenna system for 5G/WLAN applications. The system consists of two types of antenna modules: an L-shaped antenna module covering the C-band for 5G mobile applications, and a folded monopole module for the 5G/WLAN mobile application band. The experimental results show that the proposed antenna can cover the desired frequency bands with high efficiency and low envelope correlation coefficient, and it exhibits stable performance in both one-hand holding and two-hand holding modes.

Summary: This paper proposes a method to enhance the isolation of massive multiple-input multiple-output arrays using decoupling cavities (DC). The DC is made of a pure Polypropylene (PP) board with an engraved air cavity that has high transmission in the normal direction and a high insertion loss in the tangential direction of the arrays. The DC operates with a broadband response due to the low dielectric constant of the substrate. An example of a 4x4 array with an inter-element distance around half wave-length is designed to verify the proposed isolation enhancement method. The isolation of the array is enhanced to 24 dB within the bandwidth of 4.21-4.79 GHz, while the radiation characteristics of the arrays remain consistent before and after loading the DC.

Summary: This paper proposes a miniaturized MIMO antenna array based on half-mode substrate integrated waveguide (HMSIW). The operating bandwidth is widened by introducing quarter-mode on the conventional HMSIW, and the array size is further reduced by orthogonally arranging the four antenna elements using quasi-electric wall characteristics of metal via. The decoupling structure of composite neutralization lines (NLs) is used to improve the isolation of the MIMO antenna array. The fabricated and implemented 2x2 MIMO antenna array shows good agreement between simulated and measured results, with high gain and low mutual coupling levels.

Summary: Correlations and mutual couplings in antenna arrays can degrade the performance of MIMO systems. Reducing mutual coupling and correlation simultaneously is not an easy task in various multipath environments. In this study, a combination of PMS and ADS is proposed to mitigate correlations and mutual couplings in antenna arrays. Simulation and measurement results demonstrate the effectiveness of this approach.

Summary: In order to suppress coupling among patch antenna arrays and reduce out-of-band spurious, this paper proposes a feeding-decoupling network with harmonic suppression. The decoupling method is achieved by generating two decoupling paths between the feeding of an antenna and the radiating patch of an adjacent antenna. The results show that the proposed decoupling structure effectively suppresses coupling and out-of-band spurious.

The measurement results show that the antenna is well suited for FOWLP technology and can be used for phased-array modules in 5G wireless communication systems.
