| Research Abstract |
The author has tried 3 types of circularly polarized broad antennas. In the first structure, a wide-slot antenna using L-shaped probe has been proposed. This antenna has very simple and unique structure but the azimuth range of circular polarization (CP) is narrow. To improve this, a square slot antenna using separated Lprobes has been proposed. This antenna shows broadband axial ratio and wide azimuth range of CP. Finally to realize a low-profile circularly polarized broadband antenna, a patch antenna using artificial ground structure has been proposed. This antenna shows 40% of CP bandwidth at 6GHz. Finally this antenna is arrayed, and the coupling is investigated.
