Research on electromagnetic coupling between concave layout array

It is a trend to replace the traditional discrete antenna with the array plane antenna, and the new electromagnetic interference problem produced by the array plane antenna is also the focus of the current research. This paper uses both simulation and experiments to research the issue about suppression of electromagnetic interference under the condition of two array plane antenna be laid in same plane. By means of simulation, the inhibitory effect of electromagnetic coupling between two array planes and the radiation characteristics of array plane antenna are studied on condition of concave/non-concave layout. In the laboratory environment, the inhibitory effect of electromagnetic coupling between two array planes on condition of concave/non-concave layout is studied by using the small array plane. The results show that the radiation characteristics of the antenna can not be affected by the concave layout array plane antenna, and the isolation between two array planes can be promoted by 5 dB.
