Branch Line Couplers With Small Size and Harmonic Suppression Based on Non-Periodic Step Impedance Shunt Stub (SISS) Loaded Lines

Autor: Jan Coromina, Paris Velez, Jordi Bonache, Ferran Martin

Publikováno v: IEEE Access, Vol 8, Pp 67310-67320 (2020)

This paper presents branch line couplers with compact size and harmonic suppression based on non-periodic reactively loaded artificial lines. The reactive loading elements of the lines are step impedance shunt stubs (SISSs). Such elements provide tra

Application of RF-MEMS-Based Split Ring Resonators (SRRs) to the Implementation of Reconfigurable Stopband Filters: A Review

Autor: Ferran Martín, Jordi Bonache

Publikováno v: Sensors, Vol 14, Iss 12, Pp 22848-22863 (2014)

In this review paper, several strategies for the implementation of reconfigurable split ring resonators (SRRs) based on RF-MEMS switches are presented. Essentially three types of RF-MEMS combined with split rings are considered: (i) bridge-type RF-ME

Electrically Small Resonators for Planar Metamaterial, Microwave Circuit and Antenna Design: A Comparative Analysis

Autor: Miguel Durán-Sindreu, Jordi Naqui, Ferran Paredes, Jordi Bonache, Ferran Martín

Publikováno v: Applied Sciences, Vol 2, Iss 2, Pp 375-395 (2012)

Planar metamaterials and many microwave circuits and antennas are designed by means of resonators with dimensions much smaller than the wavelength at their resonance frequency. There are many types of such electrically small resonators, and the main

A High-Gain Passive UHF-RFID Tag with Increased Read Range

Autor: Simone Zuffanelli, Pau Aguila, Gerard Zamora, Ferran Paredes, Ferran Martin, Jordi Bonache

Publikováno v: Sensors, Vol 16, Iss 7, p 1150 (2016)

In this work, a passive ultra-high frequency radio-frequency identification UHF-RFID tag based on a 1.25 wavelengths thin dipole antenna is presented for the first time. The length of the antenna is properly chosen in order to maximize the tag read r

Electrically Small Resonators for Metamaterial and Microwave Circuit Design

Autor: Marta Gil, Adolfo Velez, Miguel Duran-Sindreu, Gerard Siso, Jordi Bonache, Ferran Martin, F. Aznar, Jordi Selga

Publikováno v: Passive Microwave Components and Antennas

In this chapter, different kinds of resonant-type metamaterial transmission lines based on subwavelength resonators have been presented and studied. There are several types of resonators which allow their use in the implementation of this kind of art

On-metal UHF-RFID passive tags based on complementary split-ring resonators

Autor: Ferran Martin, Jordi Bonache, Simone Zuffanelli, Gerard Zamora, Pau Aguila, Ferran Paredes

The use of complementary split-ring resonators (CSRRs) as radiating elements in low-profile on-metal ultra-high-frequency radio-frequency identification (UHF-RFID) tags is explored in this study. First, the radiation properties of the edge-coupled an
