Design of Printed Wideband dipole with High Gain and Anti-interference Characteristics

A printed wideband dipole with high gain and anti-interference characteristic is designed in this paper. The antenna is composed of two microstrip open-loop resonators, a parallel coupled line, a wideband dipole, and two radiation guide lines. The parallel coupled line is designed as an admittance converter. It is used to connect the wideband dipole and the microstrip open-loop resonator. The dipole performs not only radiator, but also a resonator of the filter. The radiation guide lines are used to increase the gain of the dipole. Simulation results show that the integrated dipole has high gain, good impedance bandwidth and out-of-band rejection characteristic.
