OMNI-DIRECTIONAL PLANAR ANTENNA

摘要

Provided is a planar antenna having omni-directional radiation patterns. The planar antenna includes a circular patch located on one dielectric substrate of the plurality of dielectric substrates; a planar transmission line applied with signals from the exterior; a signal via for coupling the circular patch with the planar transmission line and supplying the signals incoming through the planar transmission line to the circular patch; and a metal ground plane having a slot having a certain shape through which the signal via passes, and located on the dielectric substrate.
