Abstract

This paper presents a full-wave analysis of the electromagnetic problem of a three-dimensional (3-D) antenna radiating through a two-dimensional (2-D) radome. The Fourier transform is initially employed to reduce the 3-D field problem to a spectrum of 2-D problems with harmonic longitudinal field variation. The fast high-order method proposed recently is then used to analyze the radiation properties of the 2-D field problems. This fast high-order algorithm is based on the fast Fourier transform (FFT) with high efficiency and accuracy. The algorithm runs in O(Nlog(N)) operations, where N is the number of discretization points. Numerical results are presented to verify the validity and efficiency of this method for analyzing a finite dipole antenna radiating through a 2-D dielectric radome
