Solderless circularly polarized microwave antenna element

An antenna feed circuit comprising:

• a non-planar electrical conductor, wherein the non-planar electrical conductor further comprises:
• an input port for receiving a signal;
• four excitation points for outputting the signal;
• tapers from the input port to each of the four excitation points to provide ordered output signals of equal strength with phase shifts of 90° between at least one of a previous output signal and a subsequent output signal at each of the four excitation points;
• a non-planar, self-supporting feed circuit having a non-planar, self-supporting feed circuit aperture;
• a circuit cavity for containing the non-planar, self-supporting feed circuit, wherein the circuit cavity has a dielectric free circuit cavity aperture;
• a lid:
• and
• a solderless central pin connecting to the first bowl-shaped disk at a first end and the lid at a second end, and passing through the dielectric free circuit cavity aperture, the circuit aperture, and the second radiating disk aperture;
• with the two disks stacked containing crossed slots with a plurality of microstrip feed lines short circuited at one end forming delay lines together creating a wider operational matching bandwidth for outputting an orthogonal signal.
