Abstract:

A broadband anti-interference directional mono-cone antenna is designed in order to avoid electromagnetic interference sources in wireless communication. Omni-directional cone antenna is made improvement by adding shorted stub to realize mono-cone antenna directionality in H-plane. New method is different from general methods such as using array antenna or adding reflector, which will not increase the size of the antenna. The 3dB beamwidth in H-plane is wide and the return loss is less than -10dB within the frequency range of 1.7GHz ~ 6.0GHz of this antenna. The acceptable agreement of measured and simulated results shows that this kind of antenna has perfect input impedance and pattern properties.
