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.
