| Summary: | The utility model discloses an ultra wideband antenna for high precision positioning, which comprises a lower plane conducting medium, a middle guide pillar and an upper plane radiating body. The lower plane conducting medium and the upper plane radiating body are respectively made by double-sided printed boards. A feedback structure of the antenna is formed by a microstrip line on the lower plane conducting medium and the middle guide pillar. By adjusting the size and shape of the upper plane radiating body and the height and taper angle of the middle guide pillar, the antenna impedance matching with good bandwidth in required working frequency band can be realized. The ultra wideband antenna is characterized in that the frequency characteristics of the antenna are improved, the working bandwidth is expanded and the thickness of the antenna is decreased by adopting gradually varied middle guide pillar; and the ultra wideband antenna has the advantages of being made by double-sided printed boards, being fed b |
