Flexible and wearable 2.45 GHz CPW-fed antenna using This article demonstrated a fully printed CPW-fed antenna based on silver-nanoparticles for ISM that is flexible, wearable, and reversibly deformable. The proposed antenna consists of nano-silver ink, a conducting material used as a radiating patch and ground planes printed on the polyethylene terephthalate flexible substrate. A tunable microwave slot antenna based on graphene - CORE Abstract. The paper presents the experimental and modeling results of a microwave slot antenna in a coplanar configuration based on graphene. The antennas are fabricated on a 4 in. high-resistivity Si wafer, with a similar to 300 nm SiO2 layer grown through thermal oxidation.

Antenna-Integrated 0.6 THz FET Direct Detectors Based on
We present terahertz (THz) detectors based on top-gated graphene field effect transistors (GFETs) with integrated split bow-tie antennas. The GFETs were fabricated using graphene grown by chemical vapor deposition (CVD). The THz detectors are capable of room-temperature rectification of a 0.6 THz signal and achieve a maximum optical responsivity better than 14 V/W and minimum optical noise

... In [28], a tunable slot antenna based on CVD-grown graphene operating from 8 to 12 GHz has been proposed by Dragoman et al. As displayed in Figure 7a, the antenna is designed based on coplanar waveguide configuration and fabricated on the 4 inch high resistivity silicon wafer...
This technique is based on a delicately designed topology of L- and Ku- band microwave filters. The two band-pass responses are generated by a capacitively-loaded square-loop frequency selective surface and an aperture-coupled frequency … dielectric resonator antenna: Topics by WorldWideScience.org On top of the slot there is an air cavity and on top, a small portion of a hemispherical lens. The fractional bandwidth of such antennas is around 10 percent, which is good enough for heterodyne imaging applications.The new geometry makes … Best Paper Finalists — Eucap 2016 Lars Foged; Francesco Saccardi (Microwave Vision Italy); Andrea Giacomini (Microwave Vision Italy (MVI));

A tunable microwave slot antenna based on graphene. Graphene based functional devices: A short review | SpringerLink Graphene offers multiple functions of signal transmission, emission, modulation, and detection in a broad band, high speed, compact size, and low loss. Here, we have a brief view of graphene based functional devices at microwave, terahertz, and optical frequencies. Their fundamental physics and computational models were discussed as well.
Furthermore, the eectiveness of designed graphene based tapered slot antennas is revealed by comparing their performances with other existing UWB antennas.The recongurable characteristic of the antenna was obtained due to the tunable graphene conductivity. In microwave frequency range... Tunable Microwave Absorber Based on Patterned Graphene Two approaches to realize a tunable absorber based on patterned graphene metasurface are proposed in this paper. In the first approach, different from avai.The second approach, by implying the stack of graphene as the absorbing layer, can introduce a remarkable shift of the center frequency.
