An antenna system consisting of two implanted monopoles has been investigated. The proposed structure has been simulated in a cylindrical three layer limb phantom and the S11 and S21 responses of the system have been evaluated for the 0.5 to 5 GHz frequency range. This process occurred as the bone fracture that was introduced in the middle of the phantom gradually healed turning from blood to bone...
This paper will review techniques of manufacturing wearable antennas. 3D printing can be used to create flexible substrates. 3D shapes can be created which can be used to reduce the antenna size. Embroidery will also be discussed. The technique naturally lends itself to linear antennas.
A complementary frequency selective surface (CFSS) is formed by placing an array of slots in close proximity to an array of its Babinet's complement i.e. dipoles. In this paper by adding an additional layer of periodic elements (dipoles/slots) to a CFSS metasurface the coupling among the arrays is increased thus causing a decrease in the resonant frequency of this proposed structure. The decrease...
An implanted antenna system consisting of two monopoles attached on a metal plate for the monitoring of the healing of bone fractures has been investigated. The proposed structure has been simulated on a three layer body phantom model and the S2i response of the system is evaluated as the bone fracture that is introduced in the phantom gradually heals turning from blood to bone marrow and bone cortical...
Square loop CFSS are constructed by placing a layer of metallic loops on one side of the dielectric and aperture loops on the other side. Two different configurations of square loops CFSS are presented: It is shown that by shifting one layer by half the periodicity the resonant frequency of the pass band is significantly reduced. The effect of changing the dielectric thickness on both structures is...
This paper is part of a larger project which aims to investigate the fabricational and electromagnetic advantages of creating integrated antenna systems using emerging nano-manufacturing technology. It has been known for several decades that the effective permittivity of a mixture consisting of dielectric inclusions in a host dielectric can be controlled by varying the permittivity, size and spacing...
