Means of Employing Radiation Nulls in Filtennas: A Review

IEEE 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.
