Abstract: A base station antenna includes a first antenna having first and second spaced-apart columns of first radiating elements therein, which are configured to operate within a first frequency band. An active antenna system (AAS) is provided, which is configured to operate within a second, typically higher, frequency band. The AAS includes a second antenna within a space between the first and second columns of first radiating elements. These first radiating elements may include tilted feed stalks which support higher integration by enabling the first radiating elements to overhang at least a portion of the second antenna.

Abstract: A base station antenna includes an internal radome and a multi-column antenna array antenna. The internal radome can be configured with a plurality of columns, each having an outwardly projecting peak segment and each neighboring column of the internal radome can be separated by a valley. Each outwardly projecting peak segment(s) is oriented to project toward a front of the base station antenna and is positioned medially aligned over a respective column of the multi-column antenna array to thereby reduce mutual coupling of respective elements and/or columns of elements and/or provide a common near field environment for each element and/or each column.

Abstract: According to methods of performing measurements to determine a distance to a passive-intermodulation (“PIM”) source, a first RF signal comprising a first frequency and a second RF signal comprising a second frequency may be applied to a device under test. A reference signal comprising a higher-order intermodulation-product of the first frequency and the second frequency may also be generated. An output signal from the device under test and the reference signal may be digitized and a calibration measurement may be applied. A phase difference between the device under test output and the reference signal may be determined. A plurality of phase differences may be determined for multiple first frequencies, and from the plurality of phase differences, a delay may be calculated, which may be multiplied by the velocity of propagation on the medium connecting the device under test to the test equipment to determine a distance to the PIM source.
