    Interaction suppression technique for high-density antenna arrays for mm-wave 5G MIMO systems by Alibakhshikenari, Mohammad, Virdee, Bal Singh, Althuwayb, Ayman Abdulhadi, Falcone, Francisco, Limiti, Ernesto

    Published 2021
    “…High isolation between adjacent radiation elements was achieved by embedding a crisscrossed decoupling structure comprising slotted microstrip-lines and locating in the ground-plane under each slot a dielectric ring. The proposed periodic array behaves as artificial magnetic conductor (AMC) surfaces as incident waves in the substrate are fully reflected with a near zero degrees reflection phase. …”
