Abstract

A dipole antenna backed by a dielectric-filled cavity is proposed that offers reduced surface wave loss and increased air-side directive gain. These antennas are suitable for direct integration on dielectric package surfaces for system-in-a-package (SiP) implementations, and are fabricated using single-side processing. Prototype cavity-backed dipole antennas were measured at 27 GHz and demonstrated a 54% radiation efficiency and 10 dB boresight directivity. Through 3-D electromagnetic simulations, the radiation pattern is found to be mainly determined by cavity geometry while the input impedance is more sensitive to dipole parameters, and the simulations agree well with the measured antenna scattering parameters and radiation patterns
