Abstract

The occlusion of the secondary mirror will reduce the transmission efficiency of the traditional Cassegrain antenna. In this paper, a double reflection (D-R) system is designed to improve the transmission efficiency of Cassegrain antenna. Based on the three-dimensional vector reflection theorem, the influence of parameters and practical factors on transmission efficiency are analyzed in detail. According to our simulation results, the optimized D-R system can improve the transmission efficiency of traditional Cassegrain antenna up to 97.42% after taking some practical factors such as dispersion, chamfering, radius of incident beam, spindle deviation, reflectivity and transmittance into consideration. In addition, the transmission efficiency of the whole system is higher than the transmission efficiency of the traditional Cassegrain antenna under an axis offset between 0 and 20.34 mm. Compared with other complex antenna systems, our proposed system possesses a relatively simple structure, and is more practical in improving the transmission efficiency of traditional Cassegrain antenna..
