Multilevel antennae
An apparatus including a wireless communications device has an internal antenna system located within the wireless communications device. The internal antenna system includes a passive antenna set comprising at least one antenna element having at least one multilevel structure, a feeding point to the at least one antenna element and a ground plane. The feeding point and a point on the ground plane define an input/output port for said passive antenna set. The passive antenna set provides a similar impedance level and radiation pattern at two or more frequency bands such that the passive antenna set is capable of both transmitting and receiving wireless signals on selected channels. The selected channels are selectable from a plurality of channels throughout an entire frequency range within each of said two or more frequency bands.
