Abstract
A semi-direction shaped-beam antenna comprises a coaxial line, an aerial cover and a coaxial collinear antenna array. The side opening of the aerial cover is composed of at least two crossing feeding vibration generators, which are composed of one internal conductor in cylinder shape and one external conductor in tube shape respectively. The internal conductor is arranged in the axes of the external conductor. The two ends of the internal conductor are extended outside the two ends of the external conductor. The internal conductor and the external conductor in two neighboring crossing feeding vibration generators are connected in crossing. Medium slab is provided between two neighboring crossing feeding vibration generators. The internal conduction and the external conductor of the head crossing feeding vibration generator are connected to that of the coaxial line in crossing. The internal conductor of the end crossing feeding vibration generator is connected to the external conductor in short circuit. The electrical length of the vibration generator will not change due to welding. The space between vibration generators can be adjusted, thereby reducing dielectric loss and improve the efficiency and power capacity.
