“…To avoid the electromagnetic compatibility problems caused by the metallic support of the transmitter (Tx) antenna, a non-conductive PVC (polyvinyl chloride) support was manufactured, since this material has dielectric properties similar to air. This solution has already been used in other works because of its low cost and because it allows to manufacture very robust structures by assembling plumbing pipes and joints [53][54][55][56]. The effects of this type of support have been considered negligible in some studies [57].…”

This work addresses the design and experimental characterization of on-body antennas, which play an essential role within Body Sensor Networks. Four antenna designs were selected from a set of eighteen antenna choices and finally implemented for both passive and active measurements. The issues raised during the process of this work (requirements study, technology selection, development and optimization of antennas, impedance matching, unbalanced to balanced transformation, passive and active characterization, off-body and on-body configurations, etc.) were studied and solved, driving a methodology for the characterization of on-body antennas, including transceiver effects. Despite the influence of the body, the antennas showed appropriate results for an in-door environment. Another novelty is the proposal and validation of a phantom to emulate human experimentation. The differences between experimental and simulated results highlight a set of circumstances to be taken into account during the design process of an on-body antenna: more comprehensive simulation schemes to take into account the hardware effects and a custom design process that considers the application for which the device will be used, as well as the effects that can be caused by the human body.

Abstract-Due to their very high integration density, echelle grating spectrometers based on silicon nanophotonic platforms have received great attention for their applications in many areas, such as optical sensors, optical communications, and optical interconnections. The design of echelle gratings requires an effective modeling and simulation technique. Though we have used a boundary integral method to accurately analyze the polarization-dependent performance of the echelle grating, it is complicated and time-consuming for the simulation due to its large size and aperiodic structure. In the present paper, we will present a faster simulation method for the grating with twice total internal reflection facets based on a modified Kirchhoff-Huygens principle with the influence of the Goos-Hänchen shift considered. On the one hand, the presented simulation results agree well with our previous results obtained by the boundary integral method when the shift can accurately be calculated using a FDTD method. On the other hand, the biggest advantage of the new method over the existing methods is that it can also provide an insightful physical explanation for many numerical results. Finally, we will effectively apply the present method to design an on-chip spectrometer with very low noise floor.

Bandwidth is the primary resource of any communication system, as the radio spectrum is fixed. The high gain and directivity is also the major issue for a wireless network. Microstrip antenna has popular attractive features such as low profile, low cost, small size and easily integrated with RF devices; but has narrow bandwidth and low gain. This paper comprises one novel technique in order to increase the bandwidth, gain and directivity of the conventional rectangular patch antenna. In this paper gain, directivity and bandwidth of a conventional patch antenna is enhanced by increasing dielectric layer between the patch and ground through silicon micromachining technique. In Radio Frequency Identification (RFID) technology, these types of antenna provide superior performance and all the simulation has been carried out in high frequency structure simulator (HFSS).
