Abstract
A shared-aperture antenna includes a first copper metal layer; a second copper metal layer; and a dielectric substrate layer sandwiched between the first copper metal layer and the second copper metal layer. The dielectric substrate layer includes a plurality of metallized vias. The first copper metal layer is in communication with the second copper metal layer via the plurality of metallized vias. The plurality of metallized vias includes first metallized vias forming an inner circular ring and second metallized vias forming an outer circular ring with respect to the center of the antenna. The first copper metal layer, the dielectric substrate layer, the second copper metal layer, and the first metallized vias form a substrate integrated waveguide (SIW) circular cavity slot antenna. The first copper metal layer, the dielectric substrate layer, the second copper metal layer, the first metallized vias and the second metallized vias form a coaxial cavity slot antenna.
