Ultra-wideband antenna with tunable Artificial Magnetic Conductor

2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014
This paper presents a tunable Artificial Magnetic Conductor (AMC) unit cell design by means of four copper strips. With the inclusion of copper strips, the initial reflection phase of dual band AMC changes from 2.45 GHz and 5.8 GHz to single frequency of 3 GHz.

Phase Switched Screen for Radar Cloaking Based on Reconfigurable Artificial Magnetic Conductor

IEEE transactions on electromagnetic compatibility (Print), 2021
Phase switched screen (PSS) has been proposed for more than two decades for its applications on radar cloaking. However, the PSSs in most publications need a thickness of one-quarter wavelength to realize perfect cloaking at the operating frequency of ...

All-band GNSS antenna with artificial magnetic conductor

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
With the introduction of multiple GNSS service providers, antennas that cover all GNSS bands become especially important. All-band GNSS antenna must cover 1146 MHz-1610 MHz band, have high front to back ratio, and good axial ratio with large beamwidth for better satellite coverage.

Novel uniplanar flexible Artificial Magnetic Conductor

Applied Physics A, 2012
A novel flexible uniplanar Artificial Magnetic Conductor (AMC) design is presented. A prototype is manufactured and characterized under flat and bent conditions in an anechoic chamber. The designed prototype shows broad AMC operation bandwidth, polarization angle independency, and high angular stability margin when operating under oblique incidence.

Applications of the Field Transformation for Artificial Magnetic Conductors

2019 IEEE International Conference on Computational Electromagnetics (ICCEM), 2019
The Field transformation (FT) method provides a impedance control at any incidence angels, which makes it a superior method for wide-angle devices design. In this paper, a wide-angle artificial magnetics conductor (AMC) was designed by FT method and was numerically demonstrated.
