Abstract
An improved proximal cable-less communications system using at least two receivers is described. The system is significantly improved by utilizing an intentional signal path for the local oscillator signal to be radiated while maintaining the architecture of each receiver and the proximal cable-less communications system. The effectiveness of radiation can be increased by extending the length of the electrical interconnect which connects the local oscillator to the mixer. In addition, the effectiveness of radiation is increased by magnetically coupling the electrical interconnect which connects the local oscillator with the mixer with the electrical interconnect which connects the antenna and the mixer. By coupling the two electrical interconnect, the signal output by the local oscillator is induced on the electrical interconnect between the antenna and the mixer. The coupling is set such that the signal induced travels along the electrical interconnect and is radiated out of the antenna.
