Abstract

A cavity resonance antenna (CRA) with three dielectric superstrates is examined and its performance is compared to those of the single superstrate CRAs of the lowest two resonances. The broadside directivity, bandwidth, and directivity-bandwidth product of all three antennas are investigated. When compared to the single superstrate CRAs, an appropriately designed three superstrate CRA can enhance to the maximum directivity, the bandwidth, or both, a result that is reflected as more than 75% increase to the directivity- bandwidth product in some cases. Theoretical results are validated by simulation using commercial numerical electromagnetics software.
