Abstract:

A broadband high isolation dual-polarized dipole antenna element is presented.Which is suitable for the base station antenna.The parameters of the antenna are simulated and analysed by the EM simulation software HFSS.The VSWR is below 1.35 with the frequency range between 698 and 960 MHz.The port isolation is greater than 41 dB.And the antenna has a perfect miniaturization characteristics.This design provides a useful way for the design of the low-frequency-band broadband Mobile communication base station antenna.
