Compact dual-port MIMO filtenna-based DMS with high isolation for C-band and X-band applications

open access: yesEURASIP Journal on Wireless Communications and Networking, 2023
A dual-port multiple-input multiple-output (MIMO) filtenna with minimal sizes of 80 × 45 mm2 is set up in this study. Each element in this MIMO filtenna is positioned orthogonally to the one next to it to improve isolation.

Means of Employing Radiation Nulls in Filtennas: A Review

open access: yesIEEE Access
In this paper, methods for improving frequency selectivity in filter antennas by employing controllable radiation nulls (RN) are reviewed. Radiation nulls in the Gain graph help in improving the rejection of out-of-band frequencies.
