Abstract :
The radiation properties of both singly and multiply fed annular slot antennas on a dielectric/air interface have been analyzed using Galerkin´s method applied in the Hankel transform domain. The validity of our method has been confirmed through comparison with both theoretical and experimental results. The magic slot configuration has also been studied. The polarization diversity of this radiator makes it suitable for implementing a quasioptical balanced mixer
