ABSTRACT

In this paper, the microstrip array antenna is studied to replace the parabolic antenna in the directsatellite reception. A microstrip array antenna has been used in extremely limited area, but if it is appliedto practical life like a direct satellite reception antenna, we expect that it will be used in various way. First of all, if we use a microstrip array antenna for a direct satellite reception antenna, it should be guaranteedcharacteristics of broadband frequency. Therefore, the goal of this paper is designing technique an antennawhich guarantees broadband frequency band for a direct satellite reception. In this paper, the proposedmicrostrip antenna is fed by orthogonal two feed lines to a rectangular patch and a sequentially rotatedfeeding technique is designed proposed for a good axial ratio in broadband frequency band. Therectangular patch is designed to satellite reception band, and the width and length are W=L=8.9 mm (0.352λo) respectively. The antenna’s ground plane has dimensions of 250×250 mm. The experimental resultsverify that the proposed antenna had the axial ratio of above 1dB broader than that of the conventionalfeeding antenna. In order to verify the performance, a 8×8 array having two pairs was fabricated andtested. The maximum gain is 20.8 dB, the sidelobe level confirm less than .10 dB. It is verified by linkbudget calculation that C/N=6.7 dB can be obtained for domestic use if this proposed antenna is used inKoreasat reception system.
