Patent number: 11355848Abstract: An antenna arrangement that is designed to match, or approach based on a cost function, a specification includes a list of a plurality of predefined frequencies and, possibly a list of predefined bandwidths at a matching level. The antenna arrangement is designed using a plurality of predefined elements comprising a primary conductive element defined as a main trunk and a combination of secondary conductive elements selected from trunks, branches or leaves. The primary conductive element and the secondary conductive elements are defined by design parameters that comprise a susceptance that is a function of a geometry, a form factor, a main dimension, an orientation of the secondary conductive elements relative to the primary conductive element and a position of the secondary conductive elements on the primary conductive element. The antenna arrangement may be further defined to match a predefined form factor.Type: GrantFiled: June 27, 2019Date of Patent: June 7, 2022Assignee: INSTITUT MINES TELECOM—IMT ATLANTIQUE—BRETAGNE—PAYS DE LA LOIREInventor: Jean-Philippe Coupez

Patent number: 11329380Abstract: An antenna arrangement includes a conductive element configured to resonate at and above a chosen electromagnetic radiation frequency corresponding to a fundamental resonant mode. The conductive element is folded to make coupling areas intended to shift one or more of the resonant frequencies of the higher resonant modes. Each coupling area is defined related to the set of resonant frequencies according to which the antenna is supposed to work, and is formed by positioning parts of the conductive element facing each other. The location, along the conductive element, of the parts of that conductive element intended to form a given coupling area as well as the length of these parts and as the width of the gap between them when the coupling area is formed, are determined so as to provide a given increase or decrease of the resonant frequency of a given resonant mode of the conductive element.Type: GrantFiled: December 17, 2018Date of Patent: May 10, 2022Assignee: INSTITUT MINES TELECOM—IMT ATLANTIQUE—BRETAGNE—PAYS DE LA LOIREInventor: Jean-Philippe Coupez

Patent number: 10879612Abstract: 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.Type: GrantFiled: August 10, 2017Date of Patent: December 29, 2020Assignee: INSTITUT MINES-TELECOM/TELECOM BRETAGNEInventor: Jean-Philippe Coupez
