外文摘要：A novel design approach to wideband,dual-mode resonant monopole antenna with stable,enhanced backfire gain is advanced.The sectorial monopole evolves from a linear,0.75-wavelength electric prototype monopole under wideband dual-mode resonant operation.As theoretically predicted by the two resonant modes TE3/5,1 and TE9/5,1 within a 150° radiator,the operation principle is revealed at first.As have been numerically demonstrated and experimentally validated at 2.4-GHz band,the designed antenna exhibits a wide impedance bandwidth over 90.1％(i.e.,2.06-5.44 GHz),in which the stable gain bandwidth in the backfire,-x-direction(θ=90°,φ=180°)with peak value of 3.2 dBi and fluctuation less than 3 dB is up to 45.3％(i.e.,3.74-5.44 GHz).It is concluded that the stable wideband backfire gain frequency response should be owing to the high-order resonant mode in the unique sectorial monopole antennas.
