| description | A novel multiband antenna with an unbroken metal rim for wearable
applications is presented. In order to achieve a wideband behavior, minimizing at the
same time the size of the clearance area on the antenna ground plane, a novel feeding
structure is proposed. This is achieved by connecting the metal rim to the ground
plane thus allowing generating one lower-frequency resonance without occupying a
large area. An additional resonance is then obtained using a suitable shorting patch. In
this way, the proposed antenna presents a broadband behavior, while the width of the
clearance area on the ground plane is of only 2 mm. The antenna performances in
free-space and on a human phantom simulating a human body are analyzed by means
of numerical simulations. Finally, the specific absorption rate (SAR) is analyzed to
establish the antenna reliability in wearable applications. The experimental results
demonstrate superior and stable performances of the metal-rimmed antenna when it is
employed in wearable applications. |
