Abstract: Disclosed herein are exemplary embodiments of omnidirectional antenna assemblies including broadband monopole antennas. In exemplary embodiments, the antenna assembly includes a broadband monopole antenna comprising stamped and folded elements. The antenna assembly is configured to be operable with high omnidirectional pattern conformity, e.g., at frequencies from about 617 megahertz (MHz) to about 7125 MHz or frequencies from about 698 megahertz (MHz) to about 7125 MHz, etc.

Abstract: Disclosed are exemplary embodiments of omnidirectional broadband antennas. In an exemplary embodiment, an antenna generally includes a ground element, an antenna element, and an annular patch element. The antenna element may be electrically isolated from the ground element. The antenna element may include at least one portion that is substantially conical, substantially pyramidal, and/or that tapers in a longitudinal direction. The annular patch element is electrically grounded to the ground element. The annular patch element surrounds at least a portion of the antenna element and is parasitically coupled to the antenna element.
