ANTENNA DEVICE, AND ELECTRONIC EQUIPMENT USING SAME

摘要

PROBLEM TO BE SOLVED: To provide a low-profile antenna device having an excellent radiation efficiency. SOLUTION: The antenna device 6 includes: a ground board 7; a feeding part arranged on the ground board 7 in an insulated condition therefrom ; and an antenna board 9 for a signal with a prescribed wavelength connected to the feeding part and arranged above the ground board 7 almost in parallel with the ground board 7. Further, a distance 11 between an upper surface of the antenna board 9 and an upper surface of the ground board 7 is selected to be a multiple of 0.01 to 0.02 of the prescribed wavelength, and a distance 12 between the upper surface of the antenna board 9 and a lower surface of the antenna board 9 is selected to be a multiple of 3/80 to 2/8 of the distance between the upper surface of the antenna board 9 and the upper surface of the ground board 7.
