ABSTRACT:
An apparatus and method for providing a broadband antenna is disclosed. For one embodiment of the invention, a molded antenna structure is provided having a gap between electrical components on the printed circuit assembly (PCA) and an overmolding of the antenna structure. One embodiment of the invention substantially reduces the degradation of the antenna performance in wideband modes of operation compared with prior art overmolding schemes. For one embodiment of the invention, the gap between the electrical components and the overmolding is formed by implementing a “cap” (covering) over the components on the PCA such that they are substantially surrounded by air between the cap and the PCA surface.
