Ad. Greenwood et al., HYBRID FEM SBR METHOD TO COMPUTE THE RADIATION-PATTERN FROM A MICROSTRIP PATCH ANTENNA IN A COMPLEX-GEOMETRY/, Microwave and optical technology letters, 13(2), 1996, pp. 84-87
A previously introduced technique to compute the radiation of a micros
trip patch antenna on a cylindrical body of arbitrary cross section is
extended to include patch antennas mounted on complex, three-dimensio
nal bodies. The technique involves using the finite-element method (FE
M) to characterize the patch antennas, and then computing tile radiati
on pattern with the use of the reciprocity theorem and the shooting an
d bouncing ray (SBR) method with edge diffraction. The validity of the
calculation and the need for an extension to three dimensions is show
n by comparison with measured data for a waveguide-fed trihedral. Othe
r calculations show the effects of the external geometry on the radiat
ion pattern of a microstrip parch antenna. (C) 1996 John Wiley & Sons,
