Compact Ka‐band conical beam filtenna
IET Microwaves, Antennas & Propagation, 2022 Abstract A compact conical beam antenna composed by a filtering power divider (FPD) and circular open waveguide is presented. In order to reduce insertion loss in Ka‐band, the five‐way radial power divider and the cascaded filters are constructed using metallic waveguides.

Means of Employing Radiation Nulls in Filtennas: A Review
IEEE AccessIn 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.
