摘要： 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.

摘要： 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.
