Artificial magnetic conductors based on capacitive gratings

Journal of Communications Technology and Electronics, 2007
New realizations of artificial magnetic conductors (AMCs) based on two or more closely spaced capacitive gratings whose period is small relative to the wavelength are proposed. Simple formulas are derived for estimation of the resonance frequencies and frequency bands in which the proposed structures behave as AMCs.

A wideband, compact, high gain, low-profile, monopole antenna using wideband artificial magnetic conductor for off-body communications

International journal of microwave and wireless technologies, 2021
A wideband staircase pattern defected ground monopole antenna integrated with an artificial magnetic conductor (AMC) reflector has been proposed for C-band (4–8 GHz) and ITU band (8.01–8.5 GHz) applications. The integrated antenna consists of a staircase

Frequency-Reconfigurable Artificial Magnetic Conductor with Wide Tuning Range

2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI), 2023
A concept of frequency-reconfigurable artificial magnetic conductor (AMC) based on open-stub-loaded varactors with wide tuning range is presented. The design consists of a square patch with two open-stub-loaded varactors connected to two edges of the patch along one direction.

Small sized uniplanar artificial magnetic conductor

The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014
A novel design of planar Artificial Magnetic Conductor (AMC) in the C band frequency range using inter-digital capacitors is presented. The operation of the AMC is evaluated using FEM simulations. A prototype is manufactured and characterized based on reflection coefficient phase in anechoic chamber.

Textile artificial magnetic conductor for GPS applications

2012 6th European Conference on Antennas and Propagation (EUCAP), 2012
This paper presents an Artificial Magnetic Conductor (AMC) used for the GPS standard (L1/L2). This AMC will then be used to design an antenna dedicated to be integrated in the clothes. The AMC cell is a double square patch stacked in textile substrate.

Magnetic loading of artificial magnetic conductors for bandwidth enhancement

IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004
A magnetically loaded artificial magnetic conductor (Mag-AMC) providing enhanced bandwidth has been developed. The design is a variation of the Sievenpiper (Ph.D. diss., UCLA Elec. Eng. Dept., 1999) "thumbtack" structure, which makes use of a low-loss, aligned, barium-cobalt hexaferrite material in the spacer layer.

Antenna with Artificial Magnetic Conductor for Wireless Application

2019 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE), 2019
This paper discussed the recent works on Artificial Magnetic Conductor (AMC) with the antenna. Two different application for antenna with AMC have been discussed. The first application is the antenna with AMC that has been used for RFID system to detect the metal object. Without incorporating AMC with antenna the system cannot be detected. When the AMC

A size reduction technique for Artificial Magnetic Conductors

2011 Loughborough Antennas & Propagation Conference, 2011
This paper presents a new size reduction technique for Artificial Magnetic Conductors (AMC) without useful bandwidth degradation. This technique is based on the use of a slotted layer which is placed into the substrate of an AMC structure. Further, this layer allows the tuning of the operation frequency keeping the overall size of the AMC structure ...

Multiband artificial magnetic conductor surfaces

IEE Seminar on Metamaterials for Microwave and (Sub) Millimetre Wave Applications: Photonic Bandgap and Double Negative Designs, Components and Experiments, 2003
In this paper, multiband AMC surfaces have been studied using dipole arrays and polarisation independent fractal tripole arrays. Dual and triple band operation has been achieved using dipole AMCs. The angular response of the surfaces was very stable. The surface wave response of the structures has also been studied by means of dispersion diagrams and ...
