A multi-band antenna has a plurality of primary filar antenna elements and a plurality of parasitic filar antenna elements. Primary feed ends are coupled to feed signals. Parasitic feed ends are coupled to a common ground. Respective primary filar antenna elements and parasitic filar antenna elements are adjacently spaced from one another by a parasitic distance sufficiently narrow to shorten the primary and parasitic physical lengths relative to the primary and parasitic electrical lengths. The primary and parasitic filar antenna elements are capacitively coupled across the parasitic distance and can have different physical lengths. An optional additional filar antenna element has a bottom end coupled to the common ground. The additional filar antenna element can be distanced from the primary filar antenna element a separation distance sufficient to avoid capacitive coupling therebetween and can be greater than the parasitic distance. A process can obtain the parasitic distance for the antenna.
