| Abstract: | A novel bow-tie wideband antenna is presented. The design of the antenna is based on the principle of complementary antenna. The bow-tie patch is applied as the electric dipole, and the vertical wall together with the ground is equivalent to a magnetic dipole. A wide impedance bandwidth of more than 62% is achieved with S11<-10dB, from 1.52-2.89GHz. The radiation pattern is stable cross the operating band. The cross-polarization is less than -30dB and a front-to-back ratio of more than 18dB is obtained. |
