A highly decoupled and compact co-circularly polarized MIMO filtering antenna array system for vehicular communications

Amit Kumar, Sandeep Rana, Gunjan Srivastava, Akhilesh Mohan et autres

This paper presents a compact, single-layer, and highly decoupled four-element multiple-input-multiple-output (MIMO) filtering antenna array system designed for vehicular communications. A novel sequential phase feed network is developed by replacing the λ/4 transformers transmission lines with three-pole hairpin resonator-based band pass filters. …

A compact ultra-wideband bandstop filter using mu-negative and ENZ metamaterial resonators for multiple advanced wireless communication systems

Mouhssine Elbathaoui, Nawfal Jebbor, Sudipta Das, Wael Esmat Ali et autres

A compact ultra-wideband bandstop filter (UWB-BSF) based on a microstrip line and innovative complementary electrical LC (CELC)-loaded metamaterial (MTM) resonators is proposed. These MTM resonators exhibit negative effective permeability and epsilon-near-zero (ENZ) effective permittivity. The design employs a Rogers RO3006™ substrate and …
