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

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.
