Abstract：A conical logarithmic spiral antenna with wideband feed Balun is presented in this paper,which is simulated with ANSYS Electronics Desktop software.The antenna is designed to have a standing wave ratio of ≤ 2,an axis ratio of ≤3 dB,and a hemispherical pattern in the vertical plane in the frequency band from 1.2 GHz to 2.5 GHz.The simulation results show that the an-tenna has good wideband circular polarization performance and the radiation pattern is hemispherical in the full frequency band.Ac-cording to the simulation results,the prototype is machined,and the measured results are in agreement with the simulation results.
