Abstract
A hearing assistance device, such as a hearing aid, includes an antenna connected to a communication circuit through a feed-line for wireless communication. The antenna and the feed-line are configured and placed such at capacitance between their conductors is approximately minimized. In one embodiment, the feed-line includes feed-line conductors each including a major portion approximately perpendicular to an antenna conductor. In another embodiment, the feed-line includes a feed-line conductor crossing the antenna conductor, and at least one of the antenna conductor and the feed-line conductor includes a notch in the crossing area to reduce the crossing area.
