| 摘要 |
This invention relates to reducing the complexity and cost of antenna arrays and is more specifically concerned with reducing the complexity of an antenna apparatus ( 10 ). It provides an antenna array ( 62 ) made up of a vertical stack of horizontal linear structures ( 74 ) each having several groups of neighbouring array antenna elements ( 78 ), the groups ( 74 ) having variable numbers of the antenna elements ( 78 ) each connected to a transmit/receive module ( 66 ). The advantage of this configuration is that less communication modules ( 66 ), such as transmit/receive modules, are required to operate the antenna array ( 62 ), reducing the weight, power consumption and cost of an antenna apparatus ( 10 ) incorporating such an antenna array ( 62 ) without significantly limiting the capability and/or performance of a system compared to a conventional solution.
