This paper reports on the first microwave acoustic quadrature phase-shift keying (QPSK) modulator. Phase modulation is achieved via acoustic phase inversion (API) through electric field control over p...
As 6G networks push toward higher frequencies, efficient and wideband solutions are critical in the Centimeter Wave (cmWave) band to support advanced communication requirements. This paper presents a ...
This work presents an innovative, compact phase shifter integrated variable coupler in substrate-integrated waveguide (SIW) technology for millimeter-wave beam-forming applications. The phase-shifting...
This paper presents the demonstration of a circuit on substrate utilizing high-performance passive components based on the air-filled substrate-integrated waveguide (AFSIW) technology. A receiver modu...
This paper presents the first implementation of two innovative 90° hybrid couplers in Gallium Nitride (GaN) process designed for 5G applications. In a very compact design, both couplers target low ins...
The growing demand for high-data-rate transmission in modern wireless communication systems has motivated broadband wireless technologies to support increased channel capacity. This talk will present ...
This paper presents the design of 150 GHz microstrip-line Butler matrix (BM) networks realized in quartz-IPD process, including a miniaturized one using the equivalent L-C-L low-pass filter structure ...
A novel frequency-selective limiter (FSL) topology is proposed to protect receiver front-ends against high-power microwaves. The design incorporates plasma cells embedded within cylindrical cavities t...
This work presents a novel approach for scaling cold plasma generation using an SIW-based evanescent-mode (EVA) cavity resonator. The design leverages the EVA resonators’ inherent electric-field conce...
In this contribution, the behavior of an electromagnetic wave in the 140GHz range, propagating through a temperature and humidity controlled environment, is investigated. We consider the surrounding a...
