Sammanfattning

It is well known that planar self-complementary structures have a constant

input impedance and hence they are good candidates for ultra-wideband antennas.

However, introduction of a ground plane breaks the symmetry and

destroys the broadband property. In this paper, it is shown that stacking of

dielectric slabs above the antenna elements can reduce the degrading eject of

the ground plane. The dielectric slabs act as filters adding loops in the center

of the Smith chart. The results are illustrated with infinite antenna arrays

with broadside bandwidths of 4.7:1 at -13dB and of 5.5:1 at -17dB for the

cases of two and three dielectric slabs, respectively.
