Abstract
The present invention is to provide to a planar multiple band omni radiation pattern antenna having first and second patch lines printed on a planar dielectric substrate material, wherein a plurality of radiation members are formed bifurcately, symmetrically along both sides of a longitudinal axis of either patch line. Each of the radiation members comprises at least two post-shaped conductors each having a length slightly less than one-quarter wavelength of a central frequency of each operating frequency so as to form a choke and the radiation members of multi-frequency, and enable the operating frequencies not to be harmonically related.
Claims11
A planar multiple band omni radiation pattern antenna comprising:
- a planar dielectric substrate material;
- first and second patch lines, wherein the first patch line is printed on a front side of the dielectric substrate material as a signal transmission line and the second patch line is printed on a rear side of the dielectric substrate material at a position corresponding to the first patch line for serving as an extension conductor;
- and
- a plurality of radiation members formed bifurcately, symmetrically along both sides of a longitudinal axis of each of the first and the second patch lines, each of the plurality of radiation members including at least two post-shaped conductors.
