S-Band Spline-Shaped Aperture-Stacked Patch Antenna for Air Traffic Control Applications

The design of the radiating elements of a S-band planar array for air traffic control applications is addressed. Toward this end, a novel aperture-stacked patch (ASP) is proposed that, unlike the state-of-the-art layouts, exploits a spline shape on the top layer of the ASP to give the designer more degrees-of-freedom to fit user-defined requirements over the whole operative bandwidth. The elementa...
