We observe enhanced terahertz (THz) radiation generated from a Si3N4 film-coated GaAs photoconductivedipole antenna. Compared to an uncoated antenna with identical electrode geometry and optical excitationpower, the Si3N4 film-coated antenna has a higher effective DC resistance and larger breakdown voltage.As a result, the peak amplitude of generated THz radiation is significantly enhanced due to the Si3N4film-coated layer.
