Definitions
- An antenna is one of the most important components in systems of wireless broadcasting, wireless communication and wireless detection, and its structure and characteristics determine the working performance of the entire system to a great extent.
- a phased array antenna has become an important development direction of the modern antenna because of its excellent beam scanning and beamforming capacity. Radar, communication and other systems often require the phased array antenna to have the characteristics of wide working frequency band, large scanning angle, low return loss, etc.
- the antennas in some special applications often need to have strong environmental adaptability to adapt to harsh working conditions.
- the feed baluns are located at the bottom of the antenna and used to convert an unbalanced feed input by a coaxial wire to a balanced feed.
- the second metal arms are arranged at an outer upper ends of the feed baluns and fed respectively by the feed baluns.
- the number of the second metal arms is two groups, in a total of four second metal arms.
- the two groups of second metal arms are distributed symmetrically.
- a parallel doublet structure is formed between the coaxial outer conductor and the earthing metal column.
- the two groups of second metal arms are fixedly welded respectively on the coaxial outer conductor and the earthing metal column and fed by the parallel doublet structure.
