This letter presents the design of a Ku-band cross-coupled 6th order inductive post SIW ceramic filter, implemented with a novel cross-coupling between cavities 1 and 6, aiming to introduce transmission zeros to improve the out-band rejections. The originality of this letter is to consider an electrical cross-coupling embedded in the substrate via...
Conference Paper

The paper describes the design of an advanced choke ring antenna intended for a new radiation-type exposure system developed recently at IETR, France for bioelectromagnetic experiments at 60 GHz. The antenna provides a highly-uniform exposure of biological samples positioned close to the antenna aperture with the power density level three to five t...
Conference Paper
Full-text available
The paper presents the inset-fed liquid metal patch antenna with a non-contact excitation. The antenna is a classical rectangular patch operating at 2.4 GHz designed to facilitate its fabrication via injection molding technology using the flexible silicon elastomer (PDMS) and non-toxic liquid metal (Galinstan). The impact of the microfluidic channe...

This letter presents an ultrawideband contactless microstrip-to-microstrip transition connecting a conventional surface line with an embedded microfluidic line composed of a room-temperature liquid metal. The operational bandwidth of the transition spreads from about 0.8 to 7.9 GHz, which corresponds to the fractional bandwidth of $sim!!!! 165% $ ....
Conference Paper
Full-text available
Dans cet article nous présentons la conception d’un filtre SIW d’ordre 6 avec un rétrocouplage volumique entre les cavités 1 et 6. Ce rétrocouplage permet d’introduire des zéros de transmission et ainsi améliorer la réjection hors bande du filtre. L’idée consiste à réaliser un couplage électrique en couplant ces deux cavités par un tronçon de guide...
Article
Full-text available
The proliferation of user needs in the field of telecommunications, has led to overexploitation of the frequency spectrum. This led to the scarcity of frequency bands leading to a need for efficient management of frequencies. Constraints were added to the transmitting / receiving systems and in particular on the filters to prevent the saturation of...
Article
Full-text available
This special issue presents devices and the results of a tunable microwave microsystem associating RF circuits and microfluidic components. A channel is buried inside the substrate of a microstrip waveguide. This channel is located beneath a resonant stub. With this configuration a microfluidic passive tunable filter can be fabricated. Dielectric f...
Conference Paper
Full-text available
This paper presents the first results of the fabrication and characterization of a biological sensor based on two complementary parts. A microfluidic channel along with a micromachined stop-band filter are used to detect the type of fluid which flows beneath the electronic circuit. The tridimensional (3D) structure of the microstrip technology is i...
