    摘要: An antenna system for global navigation satellite systems includes a ground plane, an active antenna disposed above the ground plane, and a passive antenna disposed below the ground plane. The active antenna includes a conducting ring substantially parallel to the ground plane. A radiating conductor passes through substantially the center of the conducting ring; the ends of the radiating conductor are electrically connected to the conducting ring. An excitation pin is electrically connected to the radiating conductor. A set of reactive impedance elements is electrically connected between the conducting ring and the ground plane. The set of reactive impedance elements is disposed substantially orthogonal to the ground plane. The passive antenna is similar to the active antenna, except the passive antenna does not have an excitation pin. The antenna system effectively suppresses multipath reception, and its compact size and light weight make it suitable for integration with a surveying pole.
