In this project, the design of planar arrays composed of dipole and self-complementary elements are analyzed. It is well known that planar self-complementary structures have a frequency independent 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 project, it is shown that stacking of dielectric slabs above the antenna elements can reduce the degrading effect of the ground plane.
