A low‐profile wideband spiral antenna with multiple stopbands

open access: yesIET Microwaves, Antennas & Propagation, 2023
A low‐profile spiral antenna with three stopbands (2.55 GHz band, 3.85 GHz band, and 5.45 GHz band) is developed. The stopbands are generated using three pairs of slots cut into the spiral arms.
