Abstract

A theoretical and experimental study of the coaxial collinear (COCO) antenna are presented. The research is concentrated on the analysis of large and planar arrays which consist of foam-filled cable with plastic housings. An equivalent transmission line model is used to establish the integral equation which suitably describes COCO antenna arrays. The conjugate gradient with fast Fourier transform (CG-FFT) method is used for solving the large linear equation. To study the effect of the plastic housing, the finite difference time domain (FDTD) method is used. The computer simulation and experimental results are presented, and they are in very good agreement
