Propone una antena lineal de 1x4 parches con barrido jerárquico de formación de haces en conjunto con la conformación adaptativa de haz. Las pruebas experimentales muestran una detección eficiente de fuentes, demostrando la reducción de pasos y una identificación rápida de las fuentes.

This work presents a validation of the CLAF-SIW technology to manufacture filters for the millimeter-wave frequency range. The studied filter is a bandpass filter composed of four cavities stacked and coupled by means of iris (a total of five iris are used). Each layer is composed of a PCB of commercial thickness. The iris layers are prototyped by metallizing the slot edges, while the cavity layers contain the CLAF-SIW structure using double mushrooms as an EBG structure. The filter is obtained immediately by simply adapting the effective width of the CLAF-SIW cavity to the reference cavity, for which the effects affecting this effective value have been studied. A prototype has been fabricated with good agreement between measurement, simulation, and the ideal cavity filter response for a 36 to 37.5 GHz passband. The small discrepancies are due to the differences in the real gap between laminates and manufacturing tolerances.

This paper presents a millimeter-wave (mmWave) 5G communication system incorporating a phased array antenna and a transceiver. The testbed features a custom-manufactured planar active phased array antenna with linear polarization, housing an 8$\times$8-element planar array BeamForming Integrated Circuit (BFIC). The 27 GHz transceiver, a prototype, is built using off-the-shelf components and engineered to upconvert signals from 3.5 GHz to 27 GHz. Furthermore, an emulation of a 3GPP-inspired gNodeB, based on the FR2 5G signal, is included. A comprehensive measurement campaign was conducted in an indoor environment. Additionally, a comparison with a passive antenna was conducted for 16-QAM modulation scheme. The obtained results support that the integration of a phased array antenna is a promising technology for the future of wireless communications.

In this paper, we introduce an innovative approach for determining the complex permittivity (ε) and permeability (𝜇) of magnetodielectric composites. Our methodology uses artificial neural network (ANN) modeling to determine these key parameters from S-parameter data collected at 2.45 GHz. These measurements are performed by a novel microstrip split ring resonator (SRR)-based resonant sensor, offering enhanced precision and reliability in the estimation process.

The advent of the new fifth-generation (5G) wireless network deployments is supposing a challenge for the service providers. The high losses and propagation mechanisms detriment inherent in the millimeter wave (mmWave) band combined with the complexity of real scenarios require simulation tools that take into account all the influencing factors. In this context, we have developed an innovative simulator for deploying, analyzing and optimizing new 5G wireless networks. After performing a non-stand alone (NSA) deployment, it is able to test its performance by studying mobile users along the simulation region. This paper summarizes its main functionalities and the most outstanding characteristics. In addition, a use case of real deployment and mobility analysis is presented as an example of the simulation tool capabilities.

In this paper, the communication antennas for LUR-1 mission are presented. LUR-1 is a satellite that will orbit at 500 km above the Earth with the purpose of taking images of the planet. This satellite uses the S and X Band to communicate with the ground station. The S Band antenna has TTC (Telemetry, Tracking and Command) functions while the X Band will be used for downlink data. Anteral has developed both antennas and the mission is programmed to be launched in June 2024.
