A wireless transceiver station including an antenna device and a casing, the antenna device including at least one resonator element cooperating with the casing of the wireless transceiver station and having a shape with a low aspect ratio so as to be conformal with the casing, the at least one resonator element including a composite material and being adapted to be excited by a feed system which is positioned inside the resonator element so as to allow the antenna device to irradiate with a substantially omnidirectional radiation pattern.

Dielectric antenna device for wireless communications

An antenna device including: a first antenna assembly configured to receive first radiofrequency signals polarized according to a first polarization; a second antenna assembly configured to receive second radiofrequency signals polarized according to a second polarization orthogonal to the first polarization; and a radiofrequency signal handling assembly coupled with the first and second antenna assemblies, and configured to handle the received first radiofrequency signals separately from the received second radiofrequency signals.

Two-polarization switched-beam antenna for wireless communication systems

A method of radiating a radioelectric signal in an area of interest composed of at least two different area sectors, the method including providing at least two sector antennas arranged respective feed signals obtained from said signal; spacing apart the at least two sector antennas from each other of a distance equal to or greater than one wavelength of a radioelectric signal to be irradiated; and acting on the feed signals fed to the at least two sector antennas in such a way that a relative phase of signals transmitted by the at least two sector antennas is caused to vary in time.

Method and system for radiating a radioelectric signal through a combination of sector antennas

The method for evaluating electrical field levels in the near-zone of transmitting antennas, particularly linear array antenna widely used in cellular telephony systems, provides accurate evaluation while requiring reduced processing times and a restricted set of input data, such as physical external dimensions of the antenna, its gain and its radiation patterns in the vertical plane and in the horizontal plane.
