Summary:
Two different approaches have been used to design directive antennas: one is based on conventional Fabry-Perot (FP) resonators and another from flat Luneburg lenses. The former have been demonstrated to be highly directive and possess low side lobes for a limited band of frequencies. We have recently demonstrated that a new solution applying so called “transformation optics/electromagnetic”, can be used to convert the conventional Luneburg lens into the same geometrical profile as those of FP resonator antennas, while maintain high directivity, low side lobe level, and an enhancement of the bandwidth of operation. In this paper, A comparative study will be presented in detail between these two approaches.
