Abstract :
A coast guard patrol boat high-frequency (HF) near-vertical incident skywave (NVIS) antenna is selected as a test case to compare the electromagnetic modeling programs numerical electromagnetics code, NEC and WIPL-D code. Differences between the models and program outputs are presented. The radiation pattern predictions are compared. Agreement between the results is found to be good. Minor adjustments of the two coordinate systems of the programs are necessary. A summary of the comparison is presents.
