Abstract (en)
[origin: FR2907969A1] The antenna has an inductive element (5) and an armature (2) that is placed opposite to a mass plane (3) for providing a capacitive function. The armature and inductive element have general dimensions lower than lambda/ 10, where lambda is an operational wavelength. The armature and the inductive element define a resonator circuit at a frequency corresponding to the operational wavelength. The armature presents discontinuities which represent an origin of radiation loss during operation. An independent claim is also included for a method for fabricating a transmission/reception antenna.
