Broadband low frequency passive receiving antenna system

A broadband low frequency passive receiving antenna system that is an omnidirectional receiving antenna configured to provide broadband reception of the low frequency (LF) portion of the radio frequency (RF) spectrum, said broadband low frequency passive receiving antenna system comprising:

• an antenna that receives noise and radio wave signals;
• an antenna transmission line, wherein the antenna transmission line comprises a coaxial transmission line that acts as both a receiving antenna that receives noise and radio wave signals and a feedline;
• a matching unit to which the antenna and the antenna transmission line connect out of phase, wherein the matching unit incorporates a broadband transformer with a first end and a second end, wherein input to the first end of the broadband transformer is differential to allow a radio wave to induce a differential current, wherein the antenna transmission line connects to the second end of the broadband transformer incorporated into the matching unit;
• a coupling transformer comprising a primary coil and a secondary coil, wherein the antenna transmission line is terminated into the primary coil which isolates the antenna and the antenna transmission line, wherein the coupling transformer cancels out common noise and signals received by the antenna and the antenna transmission line, wherein the coupling transformer transforms signals that are not in phase to a lower impedance;
• and
• a radio transmission line attached to the secondary coil of the coupling transformer and connected to a radio, wherein the lower impedance signals transformed by the coupling transformer are transmitted to the radio through the radio transmission line.
