Active phased array with integrated antennas and circuits on common printed circuit cards

A phased array antenna device comprising:

• a plurality of circuit cards arranged in parallel, each circuit card comprising:
• an array of circularly polarized unit antenna elements integrated into the circuit card and arranged along an edge of the circuit card, each circularly polarized unit antenna element of the array configured to radiate electromagnetic signals directly from the edge of the circuit card;
• and
• a plurality of substrate extensions with chamfered edges formed from a substrate of the circuit card along the edge, each substrate extension corresponding to one of circularly polarized unit antenna elements.

A phased array antenna device comprising:

• a base including:
• a connector configured to couple to a backplane;
• and circuitry coupled to the connector;
• and
• a plurality of circuit cards arranged in parallel and coupled to the circuitry of the base, each circuit card comprising:
• an array of circularly polarized unit antenna elements integrated into and arranged along an edge of the circuit card and configured to radiate electromagnetic signals directly from the edge of the circuit card;
• and
• a plurality of substrate extensions with chamfered edges formed from a substrate of the circuit card along the edge, one or more of the substrate extensions corresponding to one of circularly polarized unit antenna elements.
