Patent attributes
A small size ultra-wideband (UWB) antenna comprises a radiation element, a dielectric substrate, and a dielectric element. The radiation element includes a radiation conductor, a matching element, and an antenna feeding element. A signal feeding element and a conductor plane are formed on the upper and lower surfaces of the dielectric substrate, respectively. With the matching element on the radiation conductor, the current distribution on the conductor plane is changed so that the antenna achieves a sufficient extension for both high and low impedance bandwidths. The UWB antenna is also suitable for surface-mountable fabrication process, which effectively reduces the manufacturing cost. The antenna has the advantages of small size, simple structure, and an impedance bandwidth of 7.97 GHz.
