Research on Influences of Assembly Error on Antenna Array Performance

In this paper, the influences of assembly error on the electromagnetic performance of the antenna array are studied. Taking a 4x4 antenna array as an example, this paper studies the influences of four errors on the antenna performance. And the four cases are: the antenna element spacing along two directions, inserting depth and angle of the KK connector. The conclusions based on results comparison and analysis can be used as precautions for antenna assembly.
