Efficient, cost-effective dipole antenna for radio applications

摘要

A printed dipole antenna comprises curved dipole with corresponding feed lines, which are located on opposite surfaces of a substrate are formed, are connected. In a special embodiment, the dipole antenna as a folded dipole is provided, which contains two or more connecting lines, in order thereby to permit an enlarged frequency range. Two of these dipole antennas may advantageously be adjusted to an antenna system with an improved radiation characteristic to be combined by the two dipole antennas which are so arranged that they have a different orientation. A corresponding circuit can then select the antenna, which leads to a given time supplies the better behavior.
