The antenna is occurring from 2 parts which are coaxial to a waveguide adapter and a flare section. Higher order modes are suppressed by minimum of 16 dB using pyramidal back cavity in the adapter section. The VSWR of the antenna is below 2 in range of 2 - 20 GHz. The average of 10 dB beamwidth of the antenna is about 125°with maximum deviation of 9% in the desired band. Also the phase center variation is below λ/4 for the entire band. © 2024 Elsevier B.V.
