【摘要】 本文提出一种用于基站应用的三频双极化的共口径基站天线阵列。它包括一个低频段(LB)天线和一个2 x 2中、高频段(MB、HB)天线阵列,可以覆盖1.56-2.38GHz、3.6-4GHz以及4.5-5GHz的频段。基于频率选择表面的原理,本文提出一种将频率选择表面融入到低频天线臂上,让来自中频和高频天线的辐射波能透过低频天线,减小阻塞效应。仿真结果验证了所提出的共享孔径天线阵列中的低频天线和中、高频天线在各自频段下能够实现稳定的辐射性能。更多还原

【Abstract】 This paper proposes a triband dual-polarized co-aperture base station antenna array for base station applications. It consists of a low-frequency(LB) antenna and a 2 x 2 medium/high-frequency(MB, HB) antenna array, covering the frequency bands of 1.56-2.38 GHz,3.6-4 GHz, and 4.5-5 GHz. Based on the principle of frequency selective surfaces, this paper introduces the integration of frequency selective surfaces into the low-frequency antenna arms,allowing the radiation waves from the medium and high-frequency antennas to pass through the low-frequency antenna, thus reducing the blockage effect. Simulation results validate that the low-frequency and medium/high-frequency antennas in the proposed shared-aperture antenna array can achieve stable radiation performance in their respective frequency bands.更多还原
