Abstract
An integrated distributed active radiator (DAR) device includes first and second conductors disposed adjacent to each other. The conductors define curves which close on themselves to within a distance of a gap. The first conductor first end is electrically coupled to the second conductor second end across the gap. The second conductor first end is electrically coupled to the first conductor second end across the gap. At least one active element is configured to produce a self-oscillation current at a frequency f. The self-oscillation current has a first direction in the first conductor and a second direction in the second conductor. The DAR device is configured to generate a harmonic current which has the same direction in both conductors. The DAR device is configured to efficiently radiate electromagnetic energy at a harmonic frequency and to substantially inhibit the radiation of electromagnetic energy at the frequency f.
