Optimized Omni-directional Biconical microstrip antenna

In this paper, we provide an optimized Biconical coaxial feeding microstrip antenna, based on the Transmission line model. The purpose of our study is to optimize the ceiling antenna performance, completing the signals transceiver and velocity smoothly. We set up the physical characters of antenna to achieve more gains and optimized its emission features then current, with not complex processing any more. There is data suggested that, it can get more gain at working frequency of 4. 0GHz, with respective Omni-directions, simulated by HFSS. In the actual test, the VSWR (Voltage Standing Wave Ratio) also conforms the design requirement.
