Utilizing Wideband AMC Structures for High-Gain Inkjet-Printed Antennas on Lossy Paper Substrate

Design A Flexible Antenna Integrated With Artifical Magnetic Conductor

“…There are a lot considerable work using AMC, JC-AMC is reported in [11] along with a vacuum as a substrate resonating at 5.56 GHz. In [12] the authors used ring and cross structure to design AMC with paper substrate and resonant frequency at 5 GHz. The model analysis of AMC present in this paper showed in section III following the algorithms reported in [13].…”

“…The JC-AMC structure is chosen to obtain an ultra-low profile design by reducing the distance between the antenna and the ground plane, to avoid the traditional condition of a separation greater than λ/4, as shown in figures 5, 6, 7 [14]: Also, the specific absorption rate (SAR), a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field, which is one of the main consideration for the antenna to be used near human body is reduced [12]. Finally, the AMC allows the enhancement of the frontto-back ratio which leads to increasing the realized gain.…”

A Novel Low-Profile High-Gain UHF Antenna Using High-Impedance Surfaces

“…1. This HIS geometry is chosen because it offers wide bandwidth characteristics [8]. The initial unit cell is 110x110 mm 2 , and it is printed on a 10 mm thick foamed PVC material with a dielectric constant of 2.4 and low density, around 0.55-0.74 gr/cm 3 .…”

Design of a paper-based reconfigurable frequency selective surface structure

“…Conductive ink such as silver nanoparticle ink is used in ink-jet printing, which allows for quick and inexpensive manufacturing even for complex structures [6,7,8]. In addition, paper or transparent films that are inexpensive with flexible features can be used in wallpaper applications [4,5].…”
