    • 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.
    • 射频天线通过首先从聚合材料注射成型一组宽带射频辐射元件,金属化每个宽带射频元件,以及在每个宽带射频辐射元件内安装传输线来制造射频天线。 通过注射成型至少一个,优选多个平的支撑板并且金属化每个板来制备支撑结构。 电连接器的图案形成在板上。 前板在其上具有一组附接位置,并且总体上,电导体的图案为每个附接位置提供电馈送。 宽带射频元件优选地通过超声波焊接固定到多个附接位置中的每一个上,每个宽带射频辐射元件的传输线与延伸到相应附接位置的电导体电连通。 平板连接在一起,并提供相关联的结构,例如进料。
