Abstract
The present invention relates to a horn antenna device. The horn antenna device has a step-shaped signal feed-in apparatus and a conical horn antenna. The step-shaped signal feed-in apparatus has a stepped body having multiple stairs and a connecting pin. The stepped body is adapted to radiate electromagnetic waves and receive a reflection of the electromagnetic waves. According to the structure of the step-shaped signal feed-in apparatus of the invention, the resonating modes are easy to be determined. The directivity and the signal-to-noise rate are improved. In addition, the connecting pin is directly connected to the stairs for improving the signal stability of the horn antenna device.
