Low envelope correlation coefficient, enhanced gain, and suppressed mutual coupling in compact 4-port MIMO microstrip antenna loaded with metasurface

摘要

Four port MIMO microstrip antenna is proposed for C-band wireless applications. Proposed antenna is embedded with metasurface after achieving the compactness of 17.25%. Analysis of metasurface including double negative characteristics, dispersion curve, and zeroth order frequency is presented. Furthermore, techniques for suppression of mutual coupling, suppression of cross-polarization, and enhancement of antenna gain are also described. Moreover, proposed antenna is fabricated and simulated results are validated through experimental results of fabricated prototypes.
