TWIN BEAM CONTROLLER FOR ANTENNA AND ANTENNA DEVICE USING THE SAME

摘要

The present invention relates to a twin beam controller for an antenna which adjusts a beam emitted from an antenna to be emitted in a twin beam form and an antenna device using the same. An objective of the present invention is to provide a twin beam controller for an antenna which has a simple structure and forms two twin beams directed in different directions, and an antenna device using the same. The twin beam controller for an antenna comprises: a first distributor which is connected to a first input port and has two outputs; a second distributor which is connected to a second input port and has two outputs; a cross line which is connected to one end of an output side of the first distributor and one end of an output side of the second distributor, and provides outputs crossing each other; a first hybrid coupler using the other end of the first distributor and one end of an output side of the cross line as inputs to have two outputs; a second hybrid coupler using the other end of the second distributor and the other end of the output side of the cross line as inputs to have two outputs; a first output port to output a signal outputted from one end of an output side of the first hybrid coupler; a second output port to output a mixed signal outputted from the other end of the output side of the first hybrid coupler, and one end of an output side of the second hybrid coupler; and a third output port to output a signal outputted from the other end of the output side of the second hybrid coupler.
