| Abstract: | A novel wideband unidirectional antenna composed of planar electric dipole and a shorted patch antenna is presented.The antenna is excited by a L-shaped strip feed line.A wide impedance bandwidth of 70%(SWR≤2) from the frequency of 1.87 to 3.87 GHz is achieved.Stable radiation pattern with low cross-polarization,low backlobe radiation,an antenna gain of ～7dBi is found across the entire operating bandwidth. |
