This flexible antenna provides independent and easily adjustable operating frequency design. Furthermore, the radiation patterns of this pyramidal antenna are relatively similar at the different operating frequencies. One key element of this radiating structure is its cutoff waveguide placed underneath the antenna ground plane in order to improve input ports impedance matching while minimizing the antenna rear radiation level. This paper further describes the above-mentioned antenna and gives its latest improvements. %G English %2 https://hal.archives-ouvertes.fr/hal-00530348/document %2 https://hal.archives-ouvertes.fr/hal-00530348/file/ANTEM2010_SAMI_HEBIB_245.pdf %L hal-00530348 %U https://hal.archives-ouvertes.fr/hal-00530348 %~ CNRS %~ CNES %~ LAAS %~ LAAS-MINC %~ LAAS-HYPERFREQUENCES-ET-OPTIQUE %~ INSA-TOULOUSE %~ INSA-GROUPE %~ UNIV-TLSE3 %~ UT1-CAPITOLE %~ UNIV-TLSE2
