摘要

Grouping printed wideband antennas located on cavities and capacitive coaxial probe excited by.; This invention is a multilayer printed antennas grouping patches in single configuration or stacked, separated by layers of continuous dielectric substrate, and arranged on metallic cavities. Power is supplied by capacitive coupling coaxial inserting a metal head at the end of the probe and using the first dielectric layer as separating probe-fed patch.; The location of the multilayer structure on metallic cavities configuration makes regular prints patches on a single continuous dielectric substrate, and adds the characteristics of the printed antennas embedded in cavities advantages in bandwidth and radiation characteristics.; This avoids placing the technological complexity of multilayer structures in the cavities, or inserting metal plates or posts between the patches and through the substrates.
