| چکیده | ||
| An axially corrugated horn antenna with an elliptically shaped taper is proposed for satellite communication applications. This structure is a good candidate for the feed of reflectors and also for improving the electrical properties of reflector antennas. A tapering method is used to justify the horizontal location of the corrugation profile which improves the electrical performance of the presented antenna. The simulation results of a conventional axial corrugated horn antenna with a linear taper are compared to those of the proposed antenna. These results illustrate that the cross-polarization, side-lobe level and return loss of our antenna are improved by about 16dB, 4dB and 9dB, respectively. The axial corrugated horn antenna with an elliptical tapering function is simple and low-cost as compared to the other corrugated horn antennas such as scalar (vertically) corrugated horn and subsequently, it could be preferred in commercial applications. | ||
