Abstract :
We investigate the radiation performance of dielectric rod antennas in a focal plane array. Mutual coupling between the rods is analysed as a function of spacing for E- and H-plane coupling. We show that the coupling is significant in densely packed arrays for rods with spacings less than 0.5λ especially for rods coupling in the E-plane.
