Abstract
An antenna device includes an antenna element, a wireless circuit, and electronic circuit, a substrate, a conductor, and a stub. The antenna element transmits or receives a communication signal. The wireless circuit is connected to the antenna element. The electronic circuit differs from the wireless circuit. The wireless circuit and electronic circuit are arranged in positional isolation on the substrate. The conductor is connected to the substrate to connect the antenna device to another device. The stub is arranged in a substrate part in which the wireless circuit is located. The stub has a pattern length that causes resonance at one fourth of a wavelength of the communication signal.
