A fractal monopole antenna based on the Sierpinski gasket is studied in this paper. The monopole antenna based on the Sierpinski gasket constructed through three iterations displays a multiband behaviour with three bands that are log-periodically spaced by a factor of 2, the same scale factor that defines the geometrical self-similarity of the Sierpinski fractal. The simulated as well as measured...
In this paper design curves have been investigated for broad wall longitudinal radiating slot and centered-inclined coupling slot in a Ku-band waveguide WR51 using an FEM based full wave EM analysis software, HFSS. These curves have application in the design of waveguide slot arrays. Two waveguide-fed planar slot arrays have been designed using these curves and HFSS was used to simulate the performances...
In this paper, characterization of waveguide slots in an FEM based EM analysis software has been discussed. Characterization has been done for longitudinal broad wall radiating slot and centered-inclined broad wall coupling slot. Using this characterization, a Ku band 8 times 8 planar array antenna has been designed with Elliot's design equations. Its performance was first checked in an FEM analysis...
