Pressure-bearing electromagnetic wave antenna structure for instrument while drilling, packaging device and method

The invention discloses a pressure-bearing electromagnetic wave antenna structure for a while-drilling instrument, a packaging device and a method. The pressure-bearing electromagnetic wave antenna structure comprises an antenna main body, the antenna main body is of a cylindrical structure, and a stepped hole is formed in the antenna main body; an antenna groove is formed in the outer side wall of the antenna main body, and a high-temperature wire is wound in the antenna groove; the outer side of the antenna main body is provided with a T-shaped interface and a pressure-bearing sealing interface. The T-shaped connector and the pressure-bearing sealing connector are connected through a wire. The bottom of the antenna groove is provided with a bar-shaped magnet, and the top of the antenna groove is provided with an antenna cover. And a potting sealing insulating layer is arranged in the antenna groove. The problems of signal transmission, pressure-bearing sealing insulativity, erosion corrosion resistance, vib
