ABSTRACT:
An omnidirectional ultra-wideband monopole antenna, with the characteristics of simple structure, easy fabrication and low cost, mainly comprises a ground plane, a U-shaped radiating member above the ground plane and a feeding member for feeding signals to the radiating member. The radiating member further comprises a first sub-radiating member parallel to the ground plane, with a first side edge and a corresponding second side edge, a second sub-radiating member connected to the first side edge and perpendicular to the first sub-radiating member, forming a first angle therebetween, and a third sub-radiating member connected to the second side edge to form a second angle. The second sub-radiating member and the third sub-radiating member are extended in the same upright direction above the ground plane. The antenna can provide good omnidirectional radiation patterns for frequencies across a very wide operating bandwidth.
