A Dual-Mode FM/AM Modulator Based on a Time-Varying Inverting Integrator
Azalía G. Gil, Alfonso T. Muriel-Barrado, Mario Pérez-Escribano +2
This paper presents the analysis, design, fabrication, and experimental validation of a dual-mode frequency/amplitude modulator based on a time-modulated varactor diode. By exploit…
Joint Ultra-wideband Characterization of Azimuth, Elevation and Time of Arrival with Toric Arrays
Alejandro Ramírez-Arroyo, Antonio Alex-Amor, Rubén Medina +2
In this paper, we present an analytical framework for the joint characterization of the 3D direction of arrival (DoA), i.e., azimuth and elevation components, and time of arrival (…
Joint Direction-of-Arrival and Time-of-Arrival Estimation with Ultra-wideband Elliptical Arrays
Alejandro Ramírez-Arroyo, Antonio Alex-Amor, Pablo Padilla +1
This paper presents a general technique for the joint Direction-of-Arrival (DoA) and Time-of-Arrival (ToA) estimation in multipath environments. The proposed ultra-wideband techniq…
Low-Loss Reconfigurable Phase Shifter in Gap-Waveguide Technology for mm-Wave Applications
Á. Palomares-Caballero, A. Alex-Amor, P. Escobedo +2
In this brief, we present a low-loss mechanically reconfigurable phase shifter implemented in gap-waveguide technology for mm-wave frequencies. The proposed design gives a practica…
