In this paper, the optical properties of a plasmonic nanoantenna array have been investigated. The proposed plasmonic structure presents omnidirectional resonance properties, such as omnidirectional reflection dip and omnidirectional emission peak. In addition, the reflection and emission of the plasmonic nanoantenna array with various metal/insulator/metal cavity thicknesses are theoretically and experimentally investigated. The simulation reveals a fair agreement with the experimental results.
