L'objectif de cet article est d'étudier la fabrication de pièces hybrides combinant une structure imprimée en diélectrique à faible perte et la métallisation de certaines parties de la pièce. Deux géométries d'antenne sont examinées afin d'évaluer les performances potentielles et les limites associées à la conductivité du métal déposé. Une...

In this paper, the design of a 3D printed Dielectric resonator for S-Band application is studied. A dual-band structure is targeted in order to support uplink and downlink satellite communication. A partial filling of some specific part of the DRA is used to optimize the antenna input impedance. The designed DRA exhibit a compact dimension of...

This paper presents a 3D-printed fully dielectric bi-material reflectarray with bandgap characteristics for multi-band applications. To achieve bandgap characteristics, a "1D Bragg reflector" unit cell is used. The latter is a layered structure characterized by a spatial distribution of refractive index that varies periodically along one...

This article introduces an innovative approach to significantly broaden the bandwidth of Cylindrical Dielectric Resonators. A four-element Camembert-Shaped Cylindrical Dielectric Resonator Antenna (CDRA) is presented, using an air gap separating the resonators to enhance the antenna bandwidth. The radiators, i.e., the DRA blocks, are made of...
