HORN ANTENNA HAVING STRIP LINE FEEDING STRUCTURE

摘要

PURPOSE: A horn antenna having a strip line feeding structure is provided to maintain a cross-polarization characteristic by using a strip line feeding structure instead of an additional component in a feeding process. CONSTITUTION: A horn antenna having a strip line feeding structure includes a first horn antenna unit(201), a second horn antenna unit, and a feeding unit(203). The first horn antenna unit(201) includes a first grounding unit formed with a metallic material. A first horn antenna is arranged in the inside of the first grounding unit. The first horn antenna unit(201) radiates the energy supplied from the feeding unit(203) to the first horn antenna. The second horn antenna unit includes a second grounding unit formed with the metallic material. A second horn antenna is arranged in the inside of the second grounding unit. The second horn antenna unit reflects the energy supplied from the feeding unit to the second horn antenna. The feeding unit(203) is installed between the first and the second antenna units.
