Nonreciprocal Phased-Array Antennas
J. W. Zang, A. Alvarez-Melcon, J. S. Gomez-Diaz
A phased-array antenna is a device that generates radiation patterns whose shape and direction can be electronically controlled by tailoring the amplitude and phase of the signals…
Wideband Bandpass Filters Using a Novel Thick Metallization Technology
Celia Gomez-Molina, Alejandro Pons-Abenza, James Do +4
A new class of wideband bandpass filters based on using thick metallic bars as microwave resonators, instead of common microstrip lines, is presented. These bars provide a series o…
Novel Rigorous Multimode Equivalent Network Formulation for Boxed Planar Circuits with Arbitrarily Shaped Metallizations
Celia Gomez Molina, Fernando Quesada Pereira, Alejandro Alvarez Melcon +4
The Multimode Equivalent Network (MEN) formulation has been traditionally employed for the efficient and accurate analysis of waveguide devices. In this paper, we extend the use of…
Design and Implementation of Evanescent Mode Waveguide Filters Using Dielectrics and Additive Manufacturing Techniques
Alejandro Pons-Abenza, Jose-Maria Garcia-Barcelo, Antonio Romera-Perez +6
In this contribution, we describe the design of bandpass filters using evanescent mode waveguides and dielectric resonators implemented with additive manufacturing techniques. Two…
Nonreciprocal Yagi-Uda Filtering Antennas
J. W. Zang, X. T. Wang, A. Alvarez-Melcon +1
This paper proposes a novel and compact nonreciprocal filtering antenna based on temporal modulation. The device is composed of a third order filtering section integrated into a Ya…
Coupling Matrix Representation of Nonreciprocal Filters Based on Time Modulated Resonators
A. Alvarez-Melcon, X. Wu, J. Zang +2
This paper addresses the analysis and design of non-reciprocal filters based on time modulated resonators. We analytically show that time modulating a resonator leads to a set of h…
