In this paper, a novel design method for dual-polarized multi-resonance antennas is presented for base station applications. The radiator of the antenna is configured as cross-dipoles with four thin metal strips connected to the adjacent dipole arms. The attached strips create multiple current paths and introduce additional resonant points. As a result, the bandwidth of the antennas is broadened while maintaining a very compact size. Based on this working mechanism, two multi-resonance antennas are designed, fabricated, and tested. The antennas achieve bandwidths of 46.7% and 66.7% respectively, with excellent matching capabilities. The antennas also exhibit high port isolation levels and stable radiation performances. The promising wideband performances with compact physical sizes make the antennas highly suitable for the base station applications.

具有宽带和紧凑尺寸的双极化多谐振天线，适合基站应用

在本文中，提出了一种用于基站应用的双极化多谐振天线的新颖设计方法。天线的辐射器配置为交叉偶极子，四个细金属条连接到相邻的偶极子臂。所连接的条带创建了多个电流路径，并引入了额外的谐振点。结果，在保持非常紧凑的尺寸的同时加宽了天线的带宽。基于这种工作机制，设计，制造和测试了两个多谐振天线。天线具有出色的匹配能力，分别达到46.7％和66.7％的带宽。天线还具有较高的端口隔离度和稳定的辐射性能。
