Mono/multifrequency transmission/reception antenna e.g. slot patch antenna, for e.g. mobile terminal, has armature and inductive element define resonator circuit, where armature presents discontinuities representing radiation loss origin

摘要

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.
