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.
