The analysis of a printed dipole antenna array using an enhanced Finite Difference Time Domain method

The Finite Difference Time Domain method is well suited for the solution of complex electromagnetic problems, such as antenna array characterisation, but it can suffer from the requirement of large amounts of computer resources. In this contribution, a number of enahncements to the FDTD method are applied to the analysis of an array of printed dipole antenna elements leading to a reduction in computer resources by an order of magnitude compared to standard approaches while achieving similar accuracy.
