Sierpinski Pyramidal Antenna Loaded With a Cutoff Open-Ended Waveguide

Abstract : A new pyramidal antenna for satellite application is presented. Sierpinski triangle antennas are chosen as radiating elements for their multiband features. The ground plane of the antenna is perforated and loaded with a cutoff open-ended waveguide: this original configuration leads to a good tradeoff between rear radiation and impedance matching. Ideal trap-loads are used to improve the multiband operation of the Sierpinski radiating elements. The antenna radiates circularly polarized electromagnetic fields with a large coverage at multiple operating frequencies. A specific application is given in this paper for a triband operation. Experimental results are reported and discussed.
