The design of a coplanar waveguide (CPW)-fed antenna combined with a polarization dependent artificial magnetic conductor (AMC) is presented. The gain and directivity of the embedded antenna structure, evaluated through an analysis tool based on method of moments (MoM), are improved with respect to the antenna without AMC. The current distributions of the antenna alone and of the antenna surrounded by the AMC are compared to analyze the effect of the artificial material.

“…The presented unit-cell from [4] is rescaled and the dimensions are adjusted with the aim of obtaining the AMC behavior at 5.8 GHz for TE polarized plane waves. The unitcell dimension is W 2 x W 2 = 4.38 x 4.38 mm 2 (λ 0 /12 x λ 0 /12 at 5.8GHz).…”

“…The AMC [3]- [6] will insulate the dipole antenna from the object, making possible the placement of the dipole in the Manuscript metallic objects' vicinity and in the presence of a human body without losing performance. Electromagnetic simulation tools based on finite element method (FEM) and method of moments (MoM) techniques are used.…”

The design of a novel dipole-artificial magnetic conductor (AMC) combination for UHF radio frequency identification (RFID) band, showing proper performance in the proximity of metallic surfaces, surrounding a metallic can and being conformed around the human wrist is presented. The prototypes of the dipole antenna alone and dipole antenna combined with the AMC are manufactured using laser micromachining. To the authors' knowledge, this is the first letter presenting the actual functionality of antennas and AMCs at UHF RFID frequency in order to insulate the user's body from undesired exposure to electromagnetic radiation. The experimental results of the manufactured prototypes in terms of return loss and radiation pattern measurements in an anechoic chamber are shown for comparison.Index Terms-Artificial magnetic conductor (AMC), balance-to-unbalanced transformer, dipole antenna, radio frequency identification (RFID).

“…The artificial magnetic conductor (AMC) is a type of metamaterial which introduces an in-phase reflection within the band gap of a desired frequency. AMC surface, also called the meta-surface, high-impedance surface (HIS), or reactive impedance surface, has been widely used as an artificial ground plane or reflector to enhance performance of many different antenna types while achieving profile miniaturization [3]. An artificial magnetic conductor (AMC) surface was proposed by Sievenpiper [4] and has widely investigated [5,6].…”

A CPW rectangular-ring antenna over an Artificial Magnetic Conductor (AMC) is presented in this work. The AMC is a designed as a dual-band structure having an array of unit cells and operates at 2.45GHz and 5.20 GHz. A CPW antenna uses this dual-band AMC structures as a back-plane. Performance comparison is carried out with and without incorporation of AMC. The simulated and measured results show that the combination of the AMC reflector and the antenna provide directional properties at both frequency bands. It has been found that the antenna gain increases by about 5 dB
