Cavity backed slot antenna array

By Author

A new technique for designing wideband dual-polarized cavity-backed slot antennas is presented. The structure is in the form of a double-resonant, dual-polarized slot antenna backed by a shallow substrate integrated cavity with a depth of approximately λ 0/10, where λ 0 is the wavelength in free space. The presence of the
