In this paper we investigate a method to determine the best available bandwidth for small embedded antennas. The available bandwidth depend both on the size and the position within a device, but also on the ohmic losses in the structure. Here we show a non-convex optimization problem, utilizing stored energies, and phrased as a current...

In this paper we initiate an investigation to determine the best possible position for embedded antennas with respect to their bandwidth. We focus on a device intended to operate on the 900 MHz-band. The embedded antenna and the device is electrically small, and its bandwidth performance is limited by its size. The result of the paper shows...
