Summary: This paper presents a unified model for tightly-coupled massive MIMO systems, which consist of a large number of tightly integrated antennas in a compact space. By considering mutual coupling as a friendly factor rather than a detrimental one, we show that tight coupling widens the operational bandwidth of antenna arrays, leading to a missing MIMO gain known as the bandwidth gain. Additionally, we derive the optimum spacing-to-antenna-size ratio and optimize the antenna array size to maximize achievable rate.

Summary: In this study, a wide-angle, dual-polarized frequency selective absorber (FSR) with two absorption bands located on both sides of a passband was proposed. The structure consisted of a lossy frequency selective surface (FSS), a bandpass FSS, and an air spacer in between. Simulation and experimental results demonstrated that the FSR achieved a wide operating bandwidth and stable absorption characteristics up to 50 degrees angle of incidence. The proposed FSR has potential applications in reducing the radar cross section (RCS) of communication equipment or making them stealthy.
