Systems and methods for phase-coincidential dual-polarized wideband antenna arrays

An antenna, comprising:

• a substrate;
• a plurality of unit cells coupled to a surface of the substrate, each unit cell defining a center, each unit cell including:
• a first antenna dipole including a first arm on a first side of the center and a second arm on a second side of the center opposite the first side, the first arm including a first arm end adjacent to the center and configured to receive a first voltage, the second arm including a second arm end adjacent to the center and configured to receive a second voltage;
• and
• a second antenna dipole including a third arm on a third side of the center and a fourth arm on a fourth side of the center opposite the third side, the third arm including a third arm end adjacent to the center and configured to receive a third voltage, the fourth arm including a fourth arm end adjacent to the center and configured to receive a fourth voltage;
• and
• an aperture layer coupled to the plurality of unit cells;
• wherein the plurality of unit cells are configured to transmit a radio frequency signal over a bandwidth extending between and including a first frequency to a second frequency, wherein the first frequency is approximately 3 GHz, wherein the second frequency is approximately 18 GHz, wherein a measure of isolation between the first dipole antenna and the second dipole antenna is at least 40 dB broadside from zenith across the bandwidth.
