在通信系统中,受限于信道相关性的影响,一般情况下,天线系统工作频段越低,其天线阵元间距越大,而较大的阵元间距不利于通信设备物理尺寸的降低。分析了一种阵元间距为λ/4的天线系统,其相对于常规阵元间距为λ/2的天线系统,可以实现更小的物理尺寸。选取了3种天线系统进行性能对比:8天线λ/4系统、与其尺寸相当的4天线λ/2系统以及具有相同阵元数的8天线λ/2系统,并从波束成形效果、干扰抑制能力及信道容量3个角度进行分析。仿真结果表明,λ/4天线系统在实现较小物理尺寸的同时可获得较为理想的传输性能。
In the communication system
limited by the influence of channel correlation
in general
the lower the operating frequency band of the antenna system
the larger the spacing of the antenna elements
and the larger spacing of the array elements was not conducive to the reduction of the physical size of the communication device. An antenna system with an array spacing was analyzed
which could achieve a smaller physical size than an antenna system with a conventional array spacing. Three kinds of transmit antenna systems were selected for performance comparison: 8-antenna λ /2 system
4-antenna λ /2 system (of comparable size)
and 8-antenna λ /2 system (with the same number of elements). Also their beamforming effect
interference suppression capability and channel capacity were analyzed. Simulation results show that the antenna system can achieve relatively good performance.
