Abstract :
A new horn array for parabolic cylindrical reflector antenna is proposed in this paper. By using the new horns, the linear array can suppress grating lobes when the element spacing is larger than one wavelength. The new array is adopted as the feed of a spatial power combining antenna. The gain of the antenna with new horn array feed is 1.2dB higher than that of the antenna with conventional pyramidal horn array feed.
