3-D-printed transmit-array antenna for broadband backhaul 5G links at V-band
The low cost and compactness of transmit-array antennas (TAs) make them attractive for 5G backhaul links. However, the TA advantage is less obvious when considering the broadband operation requirement. Two main factors ... -
300 GHz optoelectronic transmitter combining integrated photonics and electronic multipliers for wireless communication
THz communications systems at carrier frequencies above 200 GHz are the key to enable next-generation mobile communication networks with 100 Gbit/s wireless data rates. One of the key questions is, which carrier frequency ... -
360 nW gate-driven ultra-low voltage CMOS linear transconductor with 1 MHz bandwidth and wide input range
A low voltage linear transconductor is introduced. The circuit is a pseudo differential architecture that operates with ±0.2V supplies and uses 900nA total biasing current. It employs a floating battery technique to achieve ... -
3D procedures manual included in the app Arsim2care
This manual has been developed within the “ARsim2care: Augmented reality application in clinical simulation” Project funded by the European Union Erasmus + Program, and it is one of the project’s intellectual outputs. The ... -
A 3D ray launching time-frequency channel modeling approach for UWB ranging applications
Ultrawideband (UWB) has the ability to achieve decimetre level of ranging accuracy, hence, its wider usage nowadays in the field of positioning. In spite of the attractiveness of UWB, its performance is strongly dependent ... -
3D-printable composites for magnetic refrigeration based on Ni-Mn-In-Co shape memory alloys
Las aleaciones con memoria de forma metamagnética (MMSMA) Ni-Mn-Z (Z = In, Sn y Sb) han atraído un gran interés en las últimas décadas debido a sus propiedades asociadas con una transformación estructural llamada ... -
3D-printed 96 GHz bull’s-eye antenna with off-axis beaming
Reducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull’s-Eye ... -
The 3D-printing fabrication of multichannel silicone microreactors for catalytic applications
Microstructured reactors (MSRs) are especially indicated for highly demanding heterogeneous catalysis due to the small channel dimensions that minimize diffusional limitations and enhance mass and heat transport between ... -
3D-ray launching MIMO channel geometric estimation
The complete multiple-input–multiple-output (MIMO) channel simulation in deterministic techniques can be a computationally intensive task, due to the inherent scenario’s complexity and number of antennas. The spatial ... -
