Abstract

We propose a novel high-gain 60-GHz band planar dipole antenna for 60-GHz band 3-D system-in-package (SiP) front-end modules. To achieve high gain, we extend a dielectric substrate to main-beam direction. As a result of optimization of dielectric substrate length l, optimal substrate length l is 29.2mm(5.84λ₀) since maximum gain of 15.3 dBi is obtained. Compared with l = 1.2 [mm] (0.24λ₀), gain enhancement of 10 dB is derived. Simulation results have good agreement with measurement results. Therefore, we confirm validity of configuration of the antenna for gain enhancement at 60-GHz band.
