Abstract: An antenna includes a reflector having a front side that includes a first region and a second region that does not overlap the first region, a first column of radiating elements element that is located on the front side of the reflector and is configured to emit electromagnetic radiation within a first frequency band, the first column of radiating elements mounted to extend forwardly from the first region, and a reflection reducing component mounted forwardly of the second region, wherein the reflection reducing component is configured such that electromagnetic radiation within the first frequency band that is reflected by the reflection reducing component is weaker than electromagnetic radiation within the first frequency band that is reflected by the first region of the reflector.
