Abstract: In order to meet the needs of Ka band satellite communication system,a Ka band circularly
polarized dipole antenna array for satellite communication is designed.The antenna element is in the
form of asymmetric double arm dipole element,and the cross oscillator uses a self-phase shift structure
to achieve circular polarization.The right-hand circular polarization of the array is realized by adjusting
the rotation phase of the antenna elements.The simulation results show that the VSWR of the array is
less than 1.5except for the larger VSWR caused by the edge effect around the array.The axial ratio of
the antenna array is less than 2.3dB.When scanning at 60°,the antenna gain decreases by less than
5dB,indicating that the antenna array has a higher radiation power.As the feed source of the phased
array antenna,the antenna array has a good application prospect in satellite communication systems.
