Abstract :
In this paper, a simple radiation pattern reconfigurable printed dipole antenna is proposed. By controlling the switch states, the antenna can attain omnidirectional pattern or directional pattern. Antenna performance has been greatly improved by using harmonic trap. The return loss can be reduced to around -40 dB or even lower at the resonance point. The antenna is simulated by the full-wave electromagnetic simulator. The simulated and experimental results of the proposed antenna are investigated.
