    摘要: 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.

    摘要: High-directivity microstrip antennas comprising a driven patch and at least one parasitic element placed on the same plane, operate at a frequency larger than the fundamental mode of the driven patch in order to obtain a resonant frequency with a high-directivity broadside radiation pattern. The driven patch, the parasitic elements and the gaps between them may be shaped as multilevel and/or Space Filling geometries. The gap defined between the driven and parasitic patches according to the invention is used to control the resonant frequency where the high-directivity behavior is obtained. The invention provides that with one single element is possible to obtain the same directivity than an array of microstrip antennas operating at the fundamental mode.
