Abstract
A multiband satellite antenna is provided. The multiband satellite antenna includes a plurality of first band wave receivers and a second band wave receiver. The first band wave receiver includes a first band wave guide, and the second band wave receiver has a first receiving unit and a second receiving unit. The first receiving unit and the second receiving unit are disposed on opposite sides of an alignment line of the first band wave receivers. Each of the first receiving unit and the second receiving unit has a second band wave guide. Output ends of the first receiving unit and the second receiving unit are coupled together to combine signals received from both units into a single signal, and then the single signal is outputted as a second frequency signal. Through this design, in a high satellite density environment, dual-frequency signals from several satellites at similar elevation angles can be received by the antenna of the invention.
