Abstract
A surface mount antenna with small size and broadband is provided. The surface mount antenna includes: a substrate including a dielectric material or a magnetic material as a main material; a feed radiation conductor formed on the substrate, one end of the feed radiation conductor being a first feed end to be supplied with power, and the other end being a first open end; and a parasitic radiation conductor formed on the substrate at a distance from the feed radiation conductor, one end of the parasitic radiation conductor being a second feed end to be supplied with power from the feed radiation conductor through electromagnetic coupling, and the other end being a second open end. A region having a dielectric constant or a magnetic permeability lower than that of the main material of the substrate is provided between the feed radiation conductor and the parasitic radiation conductor.
