Broadband stacked parasitic geometry for a multi-band and dual polarization antenna

A multi-band antenna comprising:

• an S-band substrate;
• an S-band annular ring on the S-band substrate;
• an X-band substrate in the S-band substrate;
• an X-band patch located in a center of the S-band annular ring and on the X-band substrate wherein the S-band annular ring comprises a first
• upper surface, wherein the X-band patch comprises a second upper surface, and wherein the
• first upper surface is planar with the second upper surface, an electrical shorting wall separating the S-band substrate and the X-band substrate, S-band feed pins positioned along first adjoining edges of the S-band annular ring, said X-band feed pins positioned along second adjoining edges of the X-band patch wherein the S-band feed pins and the X-band feed pins are orthogonally positioned with respect to each other and comprising a ground plane adjacent to the S-band substrate and the X-band substrate.
