    • A shared antenna system (100) includes a radome (13), a metal reflector (15), a radiator array layer (14) mounting above the metal reflector, and a feeding network associated with the radiator array layer. The radiator array layer includes a plurality of radiators (23) relevant to a first and second telecommunication systems. The feeding network comprises duplexer network, phase compensating network, phase shifting network, and power splitting network. Signals from radiators are divided by the duplexer network into first RF signal for band A and second RF signal for band B. While electrical tilts of two signals are controlled independently by compensating network and phase shifting network. Two RF signals are respectively splitted to RF ports of band A and band B by the splitting network. The antenna system of the present invention can independently control electrical tilts for band A and band B, and the size thereof is minimized.
    • 共享天线系统(100)包括天线罩(13),金属反射器(15),安装在金属反射器上方的散热器阵列层(14)和与散热器阵列层相关联的馈电网络。 散热器阵列层包括与第一和第二电信系统有关的多个散热器(23)。 馈电网络包括双工器网络,相位补偿网络,相移网络和功率分配网络。 来自辐射器的信号由双工器网络划分成用于频带A的第一RF信号和用于频带B的第二RF信号。通过补偿网络和相移网络来独立地控制两个信号的电倾斜。 两个RF信号分别通过分离网络分离到频带A和频带B的RF端口。 本发明的天线系统可以独立地控制带A和带B的电倾斜,并且其尺寸被最小化。
