Abstract: A fastening structure for an antenna module assembly is disclosed. The fastening structure for an assembly includes a cover, a gasket inner seal, a circuit board including at least one antenna element, and a base. The gasket inner seal is placed over the circuit board. The gasket inner seal and circuit board are intermediately located between the cover and the base. The base includes a plurality of beveled snap-tab receiving portions integrally located about a base perimeter. The beveled snap-tab receiving portions engage an inner perimeter of the cover defined by flexible snap-tabs to fasten and matingly secure the cover to the base.

Abstract: The present invention provides an antenna unit that eliminates the need for an EMI shield to protect the sensitive components of the antenna unit's circuit board from EMI. The antenna unit includes a planar member composed of a material operating as a ground plane for the antenna unit, the ground plane defining a cavity; a circuit board secured to the ground plane, the circuit board including a platform and at least one circuit board component, the platform covering the cavity so as to enclose the circuit board component within the cavity, and an antenna positioned adjacent to the platform and in communication with the circuit board.
