A closely spaced, folded Yagi antenna design is proposed for achieving high gain in a physically compact size. It is shown that a three-element Yagi can achieve a realized gain of more than 6.7 dB, ...

By taking advantage of a wideband bow-tie antenna in the Yagi configuration, a novel multilayer-stacked ultra-wideband (UWB) Yagi antenna is proposed. First, the fundamental 3-layered UWB Yagi model ...
