A bow-tie antenna based on a slot configuration in a single metal sheet on top of a very thin flexible substrate is introduced. The antenna is constructed from two slotted right-angle triangles fed by a coplanar waveguide transmission line. The topology is very simple and extremely easy to tune in order to reach the proper characteristics after mounting on a supporting structure. A prototype is designed,...
In this work, we propose an optimal design for the crescent-slot nanoantenna for energy harvesting applications. By tuning the axial ratio of the two ellipses comprising the antenna, the band and field intensity of the nanoantenna can be controlled. Full wave electromagnetic simulations using COMSOL and HFSS have been carried out to show the efficiency of this approach.
This paper presents an electrically small meander line antenna fed by slot line transmission line. The antenna is designed for bio-medical telemetry where it operates at the Medical Implant Communication Band. Silicon substrate of high resistivity is used as a substrate. The dimensions of the antenna are λ0/75-by λ0/75. In this study, the three-layer (skin/fat/muscle) model is used to simulate human's...
This paper presents a bow-tie antenna fabricated on top of a flexible Rogers substrate. The antenna is constructed from two right-angled triangle slots which are excited by coplanar waveguide transmission lines. The length and width of the triangle arms determine the antenna's resonance location and bandwidth. The proposed structure was optimized using HFSS and results of the optimum design were verified...
In this paper, we present a CPW-fed crescent antenna for WLAN/Wi-Max applications. The antenna is fabricated using a flexible Rogers substrate, which can be mounted on any surface. The proposed antenna is composed of an outer circular slot with an inner circular patch, whose centers are non-coinciding. The patch has an additional horizontal slot along its diameter. The proposed antenna was simulated...
