| Abstract: | The coupling between antennas is an important parameter for describing the elect
romagnetic in
terference(EMI) of the airborne electronic systems. Based on the integration the
ory, the
far field radiation pattern is replaced for the antenna model, and then the airb
orne model is considered at the same time. This method can be applied to simplif
y the model and improve the efficiency with proper precision for the analysis an
d p
rediction of airborne antenna isolation. Measurement results in free space are p
resented to validate the simulation results. |

| Keywords: | airborne communication system electromagnetic interfer
