Abstract: An antenna system for a communication receiver comprising a first circuit portion located on a first circuit substrate, and a second circuit portion located on a second circuit substrate comprises an antenna which is located on the first circuit substrate and at least one circuit element of the second circuit portion being positioned in proximity to the antenna to effect interaction with the antenna. A loss cancellation element comprises a conductive sheet metal element and an insulating material enclosing the conductive sheet metal element. The loss cancellation element is affixed with an adhesive to the second circuit substrate and interposed between the antenna and the interacting circuit element to reduce the interaction between the antenna and the circuit element.

Abstract: An integral portable receiver/antenna system is provided which includes an isolation coupler element exhibiting a geometry which is substantially closed upon itself and which is situated between the receiver antenna and the input of the receiver. A portion of the antenna element is distributively coupled to a portion of the coupler element. The receiver/antenna system further includes a ground plane which is sufficiently close to a portion of the coupler element such that the ground plane is distributively coupled to the coupler element. The coupler element prevents the formation of undesired signal loss paths between the antenna and the receiver and provides for impedance matching the input of the receiver to the antenna. The coupler element also couples signals to the receiver input which would otherwise be lost to the ground plane.
