Computer programs for coupling in a finite planar rectangular waveguide antenna array
Abstract
A computer program is given to implement the equations derived in Technical Report TR787, Mutual Coupling in a Finite Planar Rectangular Waveguide Antenna Array. The aperture dimensions can be less than or equal to the feeding waveguide dimensions. Three specific uniformly spaced array lattices are considered  linear, rectangular, and isosceles triangular. For the linear and rectangular lattice cases, the Toeplitz symmetry property of the admittance matrix is utilized to save storage space and computation time. The program consists of a main program and several subroutines which calculate both the halfspace admittance and scattering matrices. The computer program is described and listed, along with sample inputoutput data.
