An antenna comprising: a longitudinal support member for supporting components of the antenna and a method of assembling such an antenna is disclosed. The components supported by the longitudinal member comprise: at least one signal feed probe configured to capacitively supply a signal to a corresponding at least one radiating patch; the at least one radiating patch mounted to at least partially wraparound the longitudinal support member; and signal supply circuitry for supplying a signal to the at least one signal feed. The signal supply circuitry is mounted on an outer surface of the inner longitudinal support member; and the longitudinal support member is formed of a conductive material and forms a ground plane for the antenna.

Antenna and method of assembly of such antenna

A method for determining a distance to a passive intermodulation source in a device under test, the method comprising transmitting at least two signals with respective different frequencies to the device under test, receiving a complex response signal from the device under test, the complex response signal comprising a passive intermodulation of the at least two signals, generating an autocorrelation matrix using the complex response signal, the autocorrelation matrix representing power information of the complex response signal, decomposing the complex response signal, using the autocorrelation matrix, into a signal component part and a noise component part and determining a distance to the passive intermodulation source in the device under test using the noise and/or signal component part.

A dual-polarization radiating element for a multiband antenna comprises a support with a high dielectric constant whose shape is roughly cylindrical, having an axis of revolution, at least a first and a second pair of dipoles printed on a first surface of the support, the dipoles of the first pair being roughly orthogonal to the dipoles of the second pair, and conductive lines, to feed each dipole, printed onto a second surface of the support. The support is placed on a flat reflector, with the cylindrical support's axis of revolution being perpendicular to the plane of the reflector.

Dual-polarization radiating element of a multiband antenna

The subject of this invention is a multiband antenna radiating element comprising a first pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a first radiating plane corresponding to a low frequency band. The radiating element also consists of at least a second pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a second radiating plan corresponding to a higher frequency band. The first and second radiating planes are parallel; the second radiating plane is positioned above the first from which it is electrically insulated and the surface of the first radiating plane covering the conducting arms of the first pair of dipoles is larger than the surface of the second radiating plane covering the conducting arms of the second pair of dipoles. The first radiating plane can be defined by a first pair of dual cross-polarization dipoles or one printed circuit dipole and the second radiating plane can be defined by a second pair of dipoles chosen from cross dipoles, butterfly dipoles and printed circuit dipoles.

Cross polarization multiband antenna

An antenna comprising a network of arrayed radiating elements, a first reflective means comprising a flat central part upon which are disposed the radiating elements and longitudinally folded edges on either side of the array of elements, and at least one second reflective means which is a choke reflector disposed outside of the space separating the radiating elements of the reflector's folded edge. The second reflective means is separated from the first reflective means by a layer of dielectric material in order to connect it to the first reflective means by way of capacitive coupling.
