Additively manufactured modular aperture antenna with shared shorting post

An antenna assembly method comprising:

• additively manufacturing an integral element as a single continuous piece of material, the integral element including:
• an antenna feed configured to receive a signal over a wide bandwidth;
• a ground plane;
• a first antenna element including a first conductive dipole arm in planar alignment with a surface of the ground plane and a second conductive dipole arm in planar alignment with the surface of the ground plane and adjacent to the first conductive dipole arm;
• a second antenna element including a third conductive dipole arm in planar alignment with the surface of the ground plane and adjacent to the second conductive dipole arm, and a fourth conductive dipole arm in planar alignment with the surface of the ground plane and adjacent to the third conductive dipole arm;
• and
• a shorting post in electrical communication with the ground plane, said shorting post further being in electrical communication, by way of only the ground plane, with the second conductive dipole arm of the first antenna element and the third conductive dipole arm of the second antenna element, wherein the shorting post is adjacent to the second conductive dipole arm of the first antenna element and the third conductive dipole arm of the second antenna element;
• and
• attaching a superstrate to the integral element;
• wherein the first conductive dipole arm, second conductive dipole arm, third conductive dipole arm, and fourth conductive dipole arm extend perpendicularly from the surface of the ground plane.
