Radiation Fields of V-Conical Antennas with Finite Length

Using mode match matching, the paper at first time analyses the radiation fields of the V-conical antennas with finite length for the first time. This approach is facilitated by dividing the space into two subregions reasonably, thus allowing use of spherical harmonic expansions in each subregion.The expansion coefficients are found by enforcing the continuity condition at the region boundary surface. The methods leads to very good agreements between the theoretical results and the simulated results,which is given by Ansoft HFSS 8.0.The conclusions. of this paper can be used for engineering design of V conical antennas.
