The central obstruction of secondary mirror causes a large loss of energy. This paper provides an optimization that a pair of cone-parabola mirrors are added in the Cassegrain optical antenna, which can fully utilize the unused energy. Taking into account of process craft, chamfers are added on the top of the cone and the connection surface between the parabola and the cone of the secondary mirror. A series of optimum structure parameters are analyzed in detail. A main point is that, after considering the reflectivity, transmission efficiency can be improved to 97.27% by our approach. This result demonstrates a better performance than traditional antenna..
