摘要： Base station antennas are provided herein. A base station antenna includes consecutive vertical columns of radiating elements. The base station antenna includes a phase shifter that is electrically connected to one of the vertical columns of radiating elements. Moreover, the base station antenna includes a phase-error compensation component that is configured to provide phase-error compensation at an input to the phase shifter based on movement of the phase-error compensation component. Related methods of operation are also provided.

摘要： Base station antennas are provided herein. A base station antenna includes a plurality of vertical columns of low-band radiating elements configured to transmit RF signals in a first frequency band. The base station antenna also includes a plurality of vertical columns of high-band radiating elements configured to transmit RF signals in a second frequency band that is higher than the first frequency band. The vertical columns of high-band radiating elements extend in parallel with the vertical columns of low-band radiating elements in a vertical direction.

摘要： Methods of identifying electrical connections between primary ports of a radio frequency circuit and primary ports of a radio are provided. A method of identifying the electrical connections includes receiving a radio frequency signal via each of the primary ports of the radio frequency circuit. Moreover, the method includes providing, by the radio frequency circuit, different responses to the radio frequency signal that is received via the primary ports, respectively, of the radio frequency circuit. In some embodiments, the different responses are different frequency responses or different delay responses. Related radio frequency circuits are also provided.
