Axial Corrugated Horn Antenna with Elliptical Tapering Function
Author(s):
Abstract:
An axially corrugated horn antenna with the elliptically shaped taper is proposed for satellite communication application. This structure is a good candidate for the feed of reflectors and improved performance of reflectors antennas electrical properties. The investigated tapering method is used to the justified horizontal location of the corrugation profile which improved the electrical performance of the presented antenna. The simulation results of a conventional axial corrugated horn antenna with a linear taper are compared to the developed antenna. These results illustrate cross-polarization, side-lobe level and return loss of the investigated antenna are improved about 16dB, 4dB and 9dB, respectively. The axial corrugated horn antenna with elliptical tapering function is simple and low-cost manufacture compared to another corrugated horn antennas such as scalar (vertically) corrugated horn and could be preferred in commercial applications because machining and machine tools of axial corrugated are more general and cheaper than the normal and scalar corrugated horn.
