A single-feed circularly polarised (CP) composite microstrip patch antenna (MPA) with a 3D conical ground plane at X-band is presented here to meet the requirements of wide beamwidth for on-board antenna structures of highly rotating bodies in projectile motion. The results of the measurement for fabricated antenna in the anechoic chamber show that a half power beamwidth $> 120 °$ and axial ratio (AR) beamwidth $> 100 °$ are achieved for right-hand CP radiation pattern in both the xoz and yoz planes with a gain of $∼ 2 dBi$ . The AR at the resonating frequency of 10.28 GHz has a low figure of 0.46 dB producing nearly smooth CP foot print with a wide AR beamwidth. The measured reflection coefficient ( $S 11$ ) of CP–MPA is $< − 15 dB$ at 10.28 GHz with an impedance bandwidth that is 8.75% of the resonant frequency. The figure of merit for cross-polarisation in the fabrication is $∼ 18 dB$ , i.e. achieved at the zenith of co-polarisation.
