OSCILLATION DEVICE AND TRANSMITTING ANTENNA DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an oscillation device and a transmitting antenna device that implement an oscillation operation matching an antenna characteristic by facilitating reference to the antenna characteristic.SOLUTION: The oscillation device includes: an antenna element having a metallic conductor having an electrical length of one wavelength of an oscillation frequency, an antenna input terminal for supplying high frequency power to the metallic conductor, and an antenna output terminal for taking out a feedback signal from an intermediate point of the metallic conductor; and a high frequency amplifier having an input terminal connected to the antenna output terminal and an output terminal connected to the antenna input terminal. The antenna output terminal has ten or more times as high an impedance as the antenna input terminal.
