Abstract

The extremely small aperture radial line slot antennas are analyzed by using the moment method technique. The differences of this analysis method from the conventional method are the circular slot arrangement, dyadic Green´s functions expanded by cylindrical eigenfunctions, consideration of periodic boundary condition in angular direction etc. The same tendency between two results of this analysis model and the reference model is presented. The computational efficiency is also expected to be enhanced compared with the conventional model.
