HOLOGRAPHIC ANTENNA ARRAYS WITH PHASE-MATCHED FEEDS AND HOLOGRAPHIC PHASE CORRECTION FOR HOLOGRAPHIC ANTENNA ARRAYS WITHOUT PHASE-MATCHED FEEDS

摘要

A holographic antenna has plurality of conductive elements arranged in a series of the conductive elements, the series of conductive elements being grouped a number of different groups of the conductive elements, each of conductive elements in each different group of conductive elements being connected via one or more tuning elements to a neighboring conductive element in each the different group of conductive elements, each different group of conductive elements comprising a holographic antenna element of the holographic antenna. A plurality of amplifiers are provided wherein each one of the plurality of amplifiers is connected at one end of each one of the different groups of conductive elements; and a feed system is provided coupling each of the amplifiers to a RF connection of the holographic antenna.
