Ultra wideband antenna |
摘要 |
An ultra-wideband antenna for operating in a frequency is disclosed wherein a monopole antenna extends from a ground plane. The monopole has an effective length L of one quarter wavelength at the lowest frequency f<SUB>1</SUB>. A dielectric resonator antenna (DRA) surrounds the monopole antenna for resonating at substantially between or at two and three times the lowest frequency f<SUB>1</SUB>, the DRA is of a height of less than ¾ L and is disposed in such a manner as being above the ground plane and either contacting or spaced therefrom by a gap G, wherein 0<=G<=0.2 H. The ultra-wideband antenna is of a much greater bandwidth than the sum of bandwidth of the monople or the DRA alone.
