Design of a low temperature co-fired ceramics (LTCC) based antenna with broadband and high gain at 60GHz bands

A dielectric resonator antenna with broad bandwidth at millimeter wave band is presented. This antenna is fabricated using low temperature cofired ceramics (LTCC) process, which is one of the most promising candidates for system-in-package (SiP) technology. The proposed antenna is an aperture coupled dielectric resonator antenna. The central region surrounded by equally spaced metallic vias act as a dielectric resonator, and an aperture for the signal feeding is located on the bottom of the resonator. The simulated antenna bandwidth is as wide as 11.7 GHz (55.4–67.1 GHz), and the measured bandwidth decreases to 9.6 GHz (56.5–66.1 GHz), which is still wider than the internationally allocated bandwidth for the communication.
