Abstract
A half-rhombic antenna includes an addressable switch at the apex. The addressable switch is opened or closed base on the operating frequency of the antenna. The addressable switch is open when operating at odd multiples of the lowest frequency and closed when operating at even multiples of the lowest frequency. The feedpoint includes a tuning element to adjust impedance within a range defined by the operating range of the switched antenna.
