Abstract:
An antenna array having a plurality of array elements, each array element comprising:first circuitry configured to conduct a common signal comprising elements of both a first frequency band and a second frequency band; second circuitry configured to conduct signals within the first frequency band separate from signals within the second frequency band; and a distributively formed circuit joining the first and second circuitry, the distributively formed circuit comprising: a first branch formed primarily of at least one conductive circuit trace configured to pass signal elements within the first frequency band and reflect signal elements within the second frequency band; and a second branch formed primarily of at least one conductive circuit trace configured to and pass signal elements within the second frequency band and reflect signal elements within the first frequency band; wherein the distributively formed circuit operates as one of a signal summer and a signal splitter.
