Chen and tsandoulas septum
WebIn this paper, a broadband septum dual circular polarized antenna with dielectric loaded is designed. In order to expand the bandwidth, the antenna uses the form of dielectric loaded in the waveguide and extends the dielectric to meet the miniaturization requirements, which can improve the Gain and the matching of waveguide. The simulation results show that … http://www.ok1dfc.com/EME/Technic/septum/W1GHZanalysis.pdf
