The antenna is designed in 30.5x35.42x0.578 mm(3) size in the operating frequency range of 3.9-10.7 GHz for S, C and X bands. The antenna gain is in the range of 3.29 dBi-5.04 dBi and the antenna efficiency is in the range of 82.56%-98.07%. As a result of the study, the antenna far-field radiation pattern is a broadband pattern and the antenna axial ratio is circular polarisation.trinfo:eu-repo/semantics/closedAccessElectronic WarfareSynthetic Aperture RadarAntenna DesignConference Object10.1109/SIU61531.2024.10600832WOS:0012978947000942-s2.0-85200834416N/AN/A
