Patent ID: 10879612

Abstract:
The invention discloses an antenna arrangement and a method of designing the same, the antenna arrangement being tuned to radiate in a plurality of bands. The antenna arrangement comprises a first conductive element which has a compact linear 2D or 3D form factor. It also comprises leaves attached to the first conductive element, the position, dimension, form factor and orientation of which are defined based on their impact on frequency shifts of the fundamental and harmonic modes, so that the antenna arrangement radiates at a plurality of predefined frequencies. The design method uses maps of hot areas where the sensitivity to the parameters defined for the leaves is maximal. Advantageously, the design method is performed in a manner which uses an orthogonality of the impacts of the parameters of the leaves vis-à-vis the different radiating modes. The antenna arrangement is compact and well adapted to applications to the IoT and consumer communication devices.
