Surface wave reduction in antenna arrays using metasurface inclusion for MIMO and SAR systems
(Advancing Earth and Space Science, 2019)
info:eu-repo/semantics/article,
An effective method is presented for suppressing mutual coupling between adjacent radiating elements which is based on metasurface isolation for multiple-input multiple-output (MIMO) and synthetic aperture radar (SAR) ...
Super-wide impedance bandwidth planar antenna for microwave and millimeter-wave applications
(MDPI, 2019)
info:eu-repo/semantics/article,
A feasibility study of a novel configuration for a super-wide impedance planar antenna is presented based on a 2 × 2 microstrip patch antenna (MPA) using CST Microwave Studio. The antenna comprises a symmetrical arrangement ...
Meta-surface wall suppression of mutual coupling between microstrip patch antenna arrays for THz-band applications
(EMW Publishing, 2018)
