ABSTRACT: Core@shell nanoparticles are advanced functional materials with modified properties combined into a single unity leading to their enhanced physico-chemical properties. In biomedical field, ...

Avista has been granted a patent for a device with a modem and dual-polarized sub-arrays that generate a collective beamwidth larger than individual beamwidths. This innovation enhances communication ...

Abstract: This paper describes the design and realization of a Massive MIMO array antenna which incorporates 16 filtering sub-arrays (i.e., array of 1-by-2 elements). The sub-arrays operates at 3.55 ...

Abstract: The design of 1×15 linear array made up of 2×2 dual-polarized microstrip sub arrays elements is presented. The linear array forms the basis of a planar array to be used for the CASA ...
