Abstract
Official abstract text for this publication.
An omnidirectional antenna is provided. The omnidirectional antenna includes a spiral antenna including a substrate, at least one upper antenna pattern formed on the substrate, and at least one lower antenna pattern formed under the substrate and connected to the upper antenna pattern; and a monopole antenna that supports the spiral antenna and that is connected to the spiral antenna. Therefore, by forming an omnidirectional antenna in a spiral antenna having an upper antenna pattern and a lower antenna pattern at an upper surface and a lower surface, respectively, of a substrate, three-dimensional current flow is available and thus omnidirectional radiation characteristics may be exhibited.
First claim
Opening claim text (preview).
What is claimed is: 1. An omnidirectional antenna, comprising: a spiral antenna comprising a substrate, at least one upper antenna pattern formed on the substrate, and at least one lower antenna pattern formed under the substrate and connected to the upper antenna pattern; wherein the upper antenna pattern and the lower antenna pattern are formed in a spiral shape; wherein a spiral final end portion of the upper antenna pattern is connected to a spiral start end portion of the lower antenna pattern; and a monopole antenna that supports the spiral antenna and that is connected to the spiral antenna. 2. The omnidirectional antenna of claim 1 , wherein the upper antenna pattern and the lower antenna pattern are connected through a connection pin that is formed in the substrate. 3. The omnidirectional antenna of claim 1 , wherein the upper antenna pattern and the lower antenna pattern are not overlapped. 4. The omnidirectional antenna of claim 1 , wherein a start end portion of the upper antenna pattern is connected to an end portion of the monopole antenna. 5. The omnidirectional antenna of claim 1 , wherein the substrate has a circular shape. 6. The omnidirectional antenna of claim 1 , further comprising an antenna cover that covers the spiral antenna and the monopole antenna.
