| Analysis of an Airborne-antenna Pattern |
|
| () |
| Abstract: |
| A radiant pattern of an airborne monopole antenna is obtained through comparing with the antenna's patterns in free space,and the effect of the aircraft on the antenna's radiation characteristics is analyzed.Based on the result,the variation of the EM fields of the airborne antenna to a fixed position in space is calculated when the aircraft is flying circlewise. |
| Key words: airborne antenna radiantion pattern EM scatter model EM field |
