This paper proposes an active calibration method for millimeter-wave beamforming arrays by estimating elements' excitations under realistic operating conditions. The method leverages far-field tr...
This paper presents a novel measurement approach for characterizing the error vector magnitude (EVM) of a transmitter using a reverberation chamber (RC). The method is demonstrated by measuring a powe...
In modern radar applications, signals are becoming more and more complex. In addition to frequency hopping, the pulses are modulated to enable pulse compression techniques and increase the range resol...
Traditional microwave filter design typically relies on iterative parameter tuning and predefined topologies, which limits design space and increases development time. This study uses a deep learning ...
Satellite networks play a crucial role across various domains, including Global communication — Delivering connectivity in remote and rural areas lacking terrestrial infrastructure, Navigation &am...
For the first time, a planar metalens-enabled semi-passive mmWave identification (mmID) system is demonstrated, achieving high detectability, wide angular coverage, and ultra-long-range operation in a...
Water-in-oil emulsions pose major challenges in areas as chemical- or offshore-systems, where droplet coalescence leads to blockage, corrosion, and equipment damage. Conventional monitoring depends on...
This work introduces a low-profile hydrogen (H₂) sensing microwave system designed for seamless integration onto metallic infrastructures, commonly needed in industrial environments. The sensor is bas...
A microwave linear-displacement sensor with two-port-quasi-reflectionless behavior is proposed. It is made up
of a balanced-circuit architecture comprising the following parts: (i) a reflective-type R...
This work presents a novel complementary impedance-shaping technique to enhance the bandwidth and input power dynamic range of RF energy harvesting rectifiers. The design utilizes two parallel branche...
