The increase of the frequency band of 3 elements Yagi-Uda antenna with narrow spacing is examined by composing element dipoles with two elliptical planes. It is shown that it is possible to make a beam in the multi frequencies or make a tunable antenna by loading variable reactance. Moreover, it is clarified that the frequency in which the gain degradation is less than 1 dB can be enhanced to about 29 percents in fractional bandwidth by employing an open-circuit dipole as a director. |
