High-gain low-profile chip-fed resonant cavity antennas for millimeter-wave bands

This letter demonstrates a novel integration approach to design high gain chip-fed antennas in V-band and W-band. An on-chip spherical dielectric resonator is integrated with a resonant cavity antenna, which resulted in high radiation efficiency and increased gain. The proposed approach minimizes the use of chip area and provides several advantages, such as, low profile and ease of assembly in comparison to similar antennas, reaching 17.8 dBi and 18.4 dBi gain for V-band and W-band, respectively.
