Abstract. S-band scanning prime
focus parabolic reflector antenna with H-plane sectorial horn array feed is
presented in this article. Calculations were made by the use of method of
moments code. Horn design was optimized for obtain overlapping phase centers in
E- and H-planes. Far fields were comparing for three different models: first
design include directly all radiating horns while the rest use array factor for
one horn in free space and one horn formed part of infinite array. The
reflection factor for power divider provided an in-phase and equal amplitude
excitation of array elements is determined.
Index terms: array-fed reflector
antenna, antenna array, horn antenna, primary antenna feed, phase center, array
factor, periodic boundary conditions.
