Abstract

A multi-band patch antenna configured for at least one of transmission or reception of electromagnetic waves in two or more frequency bands with respect to a surrounding environment, the antenna comprising: a conductive antenna element isolated from an electrical ground element of the antenna and configured for operating as a radiating surface for the electromagnetic waves with respect to the surrounding environment, the antenna element having a pair of slots dividing the antenna element into a first parasitic element, a second parasitic element, and a third element such that a first slot of the pair of slots electrically isolates the first parasitic element from the third element and a second slot of the pair of slots electrically isolates the second parasitic element from the third element; the ground element having at least one ground slot; a substrate having a selected dielectric constant and being positioned between the antenna element and the ground element, such that the antenna element is attached to a first surface of the substrate and the ground element is attached to a second surface of the substrate opposite the first surface; a feed point location of the antenna element positioned on the third element, such that only the third element of the antenna element is configured to be coupled to a signal conductor of a transmission line, such that the transmission line is configured to conduct current flow for at least one of towards the antenna element for transmission of the electromagnetic waves from the antenna element or away from the antenna element as a result of reception of the electromagnetic waves by the antenna element; and a feed point location of the ground element configured to be coupled to a ground conductor of the transmission line.
