Abstract: A base station antenna includes a radome and an antenna assembly that is mounted within the radome. The antenna assembly includes a backplane that includes a first reflector, a first array that includes a plurality of first radiating elements mounted to extend forwardly from the first reflector, a second reflector mounted to extend forwardly from the first reflector and a second array that includes a plurality of second radiating elements mounted to extend forwardly from the second reflector. The first radiating elements extend a first distance forwardly from the first reflector and the second radiating elements extend a second distance forwardly from the second reflector, where the first distance exceeds the second distance.

Abstract: Antenna arrays may include a first plurality of radiating elements responsive to respective pairs of first radio frequency signals and a second plurality of radiating elements responsive to respective pairs of second radio frequency signals. A shared radiating element is also provided, which is responsive to a corresponding pair of first radio frequency signals and a corresponding pair of second radio frequency signals. This shared radiating element may be equivalent in configuration to the first and second pluralities of radiating elements, or may have a unique configuration relative to the first and second pluralities of radiating elements. The first plurality of radiating elements and the second plurality of radiating elements can be aligned as respective first and second spaced-apart and collinear columns of radiating elements, with the shared radiating element disposed about equidistant between the first and second columns.

Abstract: An antenna includes a radiator that is electrically coupled to a feed stalk having a common-mode rejection (CMR) filter therein. The CMR filter is configured to suppress common mode radiation from the radiator by providing a frequency dependent impedance to a pair of common mode currents within the feed stalk, which is sufficient to increase a return loss associated with the pair of common mode currents to a level of greater than −6 dB across a frequency range including a frequency of the common mode radiation.
