Abstract :
In this paper, one L-branch-on-ground structure for band-notching UWB printed-elliptical-slot (PES) antenna is presented. The L branch is connected to the ground other than the antenna element. It is used for cutting the 5.8 GHz band. Compared with the U slot, T branch in the antenna element, L branch on ground is flexible because the point connecting to the ground can change in a big range. Because the antenna is PES antenna, it is compact only 24*29*1 mm3. At the same time, the paper analyzes the electromagnetic fields and presents the electronic fields and magnetic fields are resonating at different zones of the L-branch-on-ground when band-notching.
