Abstract

Transverse permittivity gradients in superstrates of extremely wideband resonant cavity antennas (RCAs) require the dielectric constant of the superstrate to change from a high value in the centre, to a low value at the edges. This paper investigates the performance of quantized permittivity gradients in such superstrates in comparison to continuous permittivity gradients. Continuous gradients are associated with high manufacturing complexity and increased cost. In this paper, two quantized permittivity distribution profiles are constructed, each with only three quantized steps to achieve comparable performance to that of piecewise-linear continuous distribution profile, while offering increased manufacturing ease. Numerical results are presented to validate the proposed concept.
