Abstract
A radio frequency antenna is fabricated by first injection molding a group of broadband radio frequency radiating elements from a polymeric material, metallizing each broadband radio frequency radiating element, and installing a transmission line within each broadband radio frequency radiating element. A support structure is prepared by injection molding at least one, and preferably multiple, flat support plates, and metallizing each plate. A pattern of electrical connectors is formed on the plates. A forward plate has a group of attachment locations thereon, and, collectively, the pattern of electrical conductors provide an electrical feed to each of the attachment locations. A broadband radio frequency radiating element is affixed, preferably by ultrasonic welding, to each of the plurality of attachment locations, with the transmission line of each broadband radio frequency radiating element in electrical communication with the electrical conductor extending to the respective attachment location. The flat plates are connected together, and associated structure, such as feeds, are provided.
