Far field radiation characteristics of linear biconical antenna array

Linear biconical antenna array is widely used in engineering application because of its directive characteristics and high radiation power. In this paper, by means of the HFSS simulation technology based on the finite element method, the far field radiation characteristics of linear biconical antenna array are studied, and the simulation results of the radiation patterns are given by changing the element number of array and its cone respectively. According to the antenna requirements for Distance Measuring Equipment (DME), a linear biconical antenna array is designed, which meets the specifications recommended by International Civil Aviation Organization (ICAO).
