Abstract

The broadband compact source approach enables detailed antenna models to be replaced by equivalent radiating surfaces for efficient installed performance analysis. The two applications discussed in this article were solved on a 2.2 GHz Core 2 Duo laptop computer with 2 GB of random access memory (RAM). The computer resources required were: GPS antenna in civilian car middot 600 MB RAM and one hour simulation time, spread spectrum antenna in Humvee middot 480 MB RAM and less than one hour simulation time. In the GPS antenna case, the compact source reduces the computational effort by a factor of ten. Savings are even greater for the spread spectrum antenna example, with a reduction of over 100.
