Abstract: Disclosed is a ceramic piezoelectric underwater detection and 5th generation (5G) mobile phone antenna, including: a ceramic cavity, a thin film, electrode feed holes and a coating, where the thin film is embedded inside the ceramic cavity; the electrode feed holes are drilled on both sides of the thin film at one end of a bottom of the ceramic cavity; the coating is coated outside the ceramic cavity for realizing omnidirectional radiation; the thin film drives the ceramic cavity to make the coating on an outer surface of the ceramic cavity generate radiation vibrations and generate electromagnetic wave radiation for communication and underwater detection.
