A 2534-GHz Eight-Element MIMO Transmitter for Keyless High Throughput Directiona

Abstract

A primary advantage of antenna arrays is their spatial selectivity, which has been widely utilized to support various applications, such as beam-steering, blocker rejection, massive multi-in--multi-out (MIMO), targeting communication, radar , and imaging. In this article, we exploit and engineer this spatial selectivity in an MIMO array for directionally secured wireless communication. We propose constellation decomposition array (CDA) and spatial carrier aggregation (SCA) schemes to achieve hig
