Abstract

A quarter-wavelength-thick unprinted dielectric slab is considered as the superstrate for a resonant cavity antenna (RCA). The behavior of the broadside directivity and radiation bandwidth is numerically investigated. It is shown that by properly choosing the superstrate's lateral dimensions, the bandwidth of RCA can be enhanced as compared to the classical designs. Computed results predict an increase in 3-dB directivity bandwidth up to 31% and peak directivity of 15 dBi at 11.5 GHz, by employing a single superstrate with permittivity of 4.4.
