The failure of slopes due to various natural processes or extensive mining activities is a common problem that has an adverse impact on the environment and may result in severe casualties. Despite taking all the geotechnical considerations for the safe design of slopes, there could be unpredictable slope failure because of unexpected weather, seismic activities, or involvement of unidentified geological structures. Thus, continuous monitoring, forecasting, and warning of slope failures are imperative to save lives and property from devastation.

A conformal reflective metasurface fed by a dual-band multiple-input multiple-output (MIMO) antenna is proposed for low-cost beam steering applications in 5G Millimeter-wave frequency bands. The beam steering is accomplished by selecting a specific port of MIMO antenna. Each MIMO port is associated with a beam that points in a different direction due to a conformal reflective metasurface.

This paper examines a multiple-input multiple-output (MIMO), circularly polarized (CP) dielectric resonator antenna for UWB systems. Compact form factor, high gain, wideband response, improved port isolation, and high data rates are the major design goals.
