The antenna can work in the double frequency band between 806~960 and 1710~2500MHz effectively. The antennas return loss is less than -10db and the gain can reach 5dB. According to the simulation optimization data, I construct an experiment model of Omni-directional radiation ceiling antenna. By using software Wireless Mon and hardwares such as vector network analyzer, routers, laptop computer, the antennas return loss, radiation pattern and gain are measured. It is shown that the measured data has a good consistency with the simulation results. This paper also made all-round study to the antennas physical properties for different geometric parameters. The final designed antenna has good engineering application. Key words: Indoor Omni-directional ceiling antenna；Ansoft HFSS.
