This article explores a novel type of antenna — dielectric resonator antennas (DRAs) based on whispering-gallery-mode (WGM) nanophotonic resonators, which demonstrate exceptionally high resistance to electromagnetic interference (EMI) and are entirely free from metallic components. Due to the ultra-high quality factors of WGM resonators and the effective overlap between radio-frequency and optical fields inside the dielectric resonator, optical signal modulation by an RF field is achieved without the use of metal electrodes. The paper discusses the operating principles, modulation parameters, and implementation schemes of such antennas, highlighting their potential for the development of highly sensitive, compact, and EMI-immune next-generation radio-photonic antenna systems.
