Abstract

The radiation characteristics of an HF antenna on metallic airframe of the AH-64 Apache helicopter is analysed using the FDTD method with the recently introduced Berenger Perfectly Matched Layer (PML) absorbing boundary conditions (ABCs). The antenna considered is an experimental 14 inches 'towel bar' used in the 2-30 MHz band. A companion 24 inches HF antenna is mounted on the opposite side of the helicopter tail boom. Finally, the FDTD predictions are found to compare well with experimental results from an operational Apache helicopter and with measured data obtained using an approximate 10:1 scale model of the Apache.
