Antenna

Abstract

The present invention provides an antenna, which includes a substrate, at least one radiating element and at least one reflecting element. The at least one radiating element is placed on the substrate at an inclined angle, and the at least one reflecting element is also placed on the substrate. The signals reflected by the at least one reflecting element substantially form an omni-directional radiation pattern through aggregation of overlapping patterns.
