ANTENNA OF INVERTED F ANTENNA TYPE INTEGRATED INTO A PRINTED CARD, AND SYSTEM

摘要

An IFA type antenna is integrated into a printed card, the printed card having a main-extension plane. The IFA type antenna has a first electrically conducting element, serving as earth plane, a second electrically conducting element, serving as radiating element of the antenna, an electrically conducting connection, serving to short-circuit the first electrically conducting element and the second electrically conducting element, and an excitation element being in electrical contact with the second electrically conducting element. The second electrically conducting element has a first part, a second part and a third part in various planes of the printed card.
