Abstract(English):

The invention relates to an antenna device and a wireless apparatus including the same. The antenna device includes a feeding element connected to a feed point, and a radiating element disposed at a distance from the feeding element. The feeding element is coupled with the radiating element by electromagnetic field coupling to feed the radiating element so that the radiating element functions as a radiating conductor. When Le21 indicates an electrical length that imparts a fundamental mode of resonance to the feeding element, Le22 indicates an electrical length that imparts a fundamental mode of resonance to the radiating element, and lambda indicates a wavelength on the feeding element or the radiating element at a resonance frequency of the fundamental mode of the radiating element, Le21 is less than or equal to (3/8)*lambda, and Le22 is greater than or equal to (3/8)*lambda and less than or equal to (5/8)*lambda when the fundamental mode of resonance of the radiating element is a dipole mode, or greater than or equal to (7/8)*lambda and less than or equal to (9/8)*lambda when the fundamental mode of resonance of the radiating element is a loop mode.
