In this paper, the impact of the ground plane reduction imposed by modern wireless terminals on the antenna performance is evaluated. Numerical results in terms of antenna efficiency andQ-factor are discussed for two different antenna geometries.
The need in biological telemetry relevance has been growing steadily for many years. A localization system, working in the SRD (Short Range Devices) frequency band of 863870MHz dedicated to the laboratory mice, is presented in this paper. It is …
In this paper, the effects of geometrical perturbations on the geometry of a reference fractal antenna have been carefully analyzed to provide a set of analytic rules for describing the resonant behavior of the antenna. As regards to the antenna …
