VHF/UHF ANTENNA WITH OMNIDIRECTIONAL RADIATION AND SWEEPING A WIDE FREQUENCY BAND

摘要

The invention relates to an antenna (1) for transmitting/receiving at one or more given operating frequencies, comprising: - a ground plane (3), - a first layer (10), positioned above said ground plane, comprising a source strip (11) having a dimension (H) less than or equal to λ/2, where λ is an operating wavelength, - a second layer (20), attached on the first layer (10), comprising a magnetic resonator configured to provide an inductive coupling with the source strip (11), and - a third layer (30), attached on the second layer (20), comprising an electrical resonator configured to produce a capacitive coupling with the source strip (11).
