Antenna structure and device for metal environment

An antenna device for metal environment, comprising:

• a radio frequency chip;
• a substrate, configured to have a first surface, a first lateral surface and a second lateral surface respectively connected to two lateral sides of the first surface along a first direction, and extended along a third direction, a third lateral surface and a fourth lateral surface respectively connected to two lateral sides of the first surface along a second direction, and extended along the third direction, and a second surface arranged opposite to the first surface along the third direction, and connected to the first lateral surface, the second lateral surface, the third lateral surface and the fourth lateral surface;
• and
• an antenna structure, formed onto the substrate and electrically coupled to the radio frequency chip, the antenna structure comprising:
• a radiating conductor, formed on the first surface, the radiating conductor defining a first hollow structure and a second hollow structure, wherein one end of the first hollow structure extends to a first side of the radiating conductor, and one end of the second hollow structure extends to a second side of the radiating conductor;
• a ground conductor, formed on the second surface, and electrically connected to the radiating conductor;
• and
• a connecting conductor, electrically coupled to the ground conductor and the radiating conductor.
