Abstract :
A novel radiating element is presented which can provide simultaneously a large bandwidth and high gain. It consists of four identical patches uniformly displayed within a rectangular aperture (2*2), and fed electromagnetically by a driven patch etched on a lower substrate. It is shown that a good coupling with the parasitic patches is obtained, causing a large bandwidth, and that the resonance modes of each patch are excited in phase, giving a high gain. Its structural simplicity and superior performance make this element an attractive candidate for large phase arrays.<>
