摘要：
Antennas with dual linear slant polarization over a wide band are necessary for modern personal communication base-station applications. A 45 degrees polarization diversity antenna element constructed by novel Umbrella-shaped dipoles is presented in this paper. The antenna has a half-power beam width of 63 degrees +/- 5 degrees in the horizontal plane by designing a reflector over a bandwidth of 1710 to 2170MHz, which covers not only 3G frequency band(1920-2170MHz) but also DCS band (1710-1880MHz) and PCS band (1850-1990MHz). In addition the worst-case isolation between polarizations is 30dB and the front-to-back ratio is more than 300 over the above frequency band.
