  • Method for achieving multiple beam radiation vertical orthogonal field coverage by means of multiple feed-in dish antenna
    Patent number: 9948008
    Abstract: A method for achieving multiple beam radiation vertical orthogonal field coverage by means of multiple feed-in dish antenna, comprising using a total metallic disc and plural feed-in antenna components, wherein it is possible to generate multiple sets of radiation beams by applying multiple sets of feed-in antenna components, and the coverage ranges created by different radiation beams may uniformly distribute there between so as to generate multiple communication service coverage areas. Moreover, since the field formed by the reflection of the total metallic disc is characterized in vertical orthogonality, advantages such as effectively increased coverage, improved energy utilization and radiation beam switches or the like can be provided.
