An antenna array is described herein that is suitable for dual-band GPS reception. The antenna array includes a plurality of dipole antennas arranged in a circular pattern. The antenna array further includes a feed network, separated from the dipole antennas by an insulating plate, and that passes electrical signals output by the dipole antennas to a feed line. The feed network comprises a central plate in contact with the feed line, and a plurality of arms aligned with the dipoles and extending from the center plate toward the outer edges of the circular pattern. The arms cross over slots in each of the dipole antennas. Electromagnetic waves that impinge on the dipoles induce signals that travel down the slots in the dipoles and couple to the arms of the feed network where the arms cross over the slots. The signals then travel along the feed network to the feed line.
