摘要： An antenna assembly includes a plurality of antenna elements disposed in a circular pattern and equidistant from each other in angular separation relative to a common reference point at a center of the circular pattern. The antenna assembly may include or be operably coupled to a phase control module configured to apply selected phase fronts to each of the antenna elements to generate constructive and destructive interference patterns to define a directive beam in a desired direction. The selected phase fronts may include no phase adjustment, a positive phase adjustment value and a negative phase adjustment value, the positive and negative phase adjustment values each having a same magnitude.

摘要： An antenna assembly includes a plurality of active antenna elements disposed in a first linear array along a reference line and equidistant from each adjacent antenna element by a first linear distance, and a plurality of passive antenna elements disposed in a second linear array extending parallel to the reference line such that each passive antenna element is a second linear distance away from a corresponding one of the active antenna elements. The antenna assembly includes or is operably coupled to a phase control module configured to apply selected phase fronts to selected ones of the antenna elements to generate constructive and destructive interference patterns to define a directive beam in a desired direction in a range between about 0 and 180 degrees relative to the reference line.

摘要： A method of interference mitigation may include receiving a desired signal from an asset of the system at an antenna assembly and associating the desired signal with relative phase distribution information based on a relative location of origin of the desired signal where the relative phase distribution information is predetermined for the antenna assembly. The method further includes receiving an interfering signal and associating the interfering signal with relative phase distribution information based on a relative location of origin of the interfering signal where the desired signal and the interfering signal forming a received signal set. The method further includes normalizing signals of the received signal set to respective relative phases associated with each respective relative location of origin, and performing interference cancellation of the interfering signal based on the normalized signals.

摘要： An antenna assembly includes a driven element, a first set of antenna elements disposed a first distance from the driven element such that each element of the first set of antenna elements is equidistant from adjacent elements of the first set of antenna elements, and a second set of antenna elements disposed a second distance from the driven element such that each element of the second set of antenna elements is equidistant from adjacent elements of the second set of antenna elements, the second distance being larger than the first distance. The antenna assembly includes or is operably coupled to a selector module configured to select one element of the first set of antenna elements as a selected director, and select one element of the second set of antenna elements as a selected reflector by effectively shortening a length of the selected director and effectively lengthening the selected reflector.
