Abstract
An integrated antenna and electromagnetic (EM) noise shield apparatus for use with a radio frequency communicating device and EM noise generating electronic equipment housed within a generally cylindrical outer glass enclosure or bezel of wireless utility meter. A flexible printed circuit (PC) board has an upper region and a lower ground plane region. A radiating element is defined on the PC board in the upper region. A metal ground plane component has a first portion having the shape of a circle segment and a second orthogonal portion. The ground plane component is mechanically fixed and electrically connected to the ground plane region of the PC board, with the orthogonal second portion being proximate to and shielding the radiating element. The ground plane component and the ground plane portion of the PC board define an electromagnetic shield for electromagnetic emissions between EM noise generating electronic equipment housed within said outer bezel and the radiating element.
