A small antenna with high isolation characteristics is designed and evaluated. Since the antenna provides lateral radiation, the antenna is suitable for the wireless file-transfer system, and it can be integrated into surface-mount package. The characteristics of the fabricated antenna meet the required gain of 6 dBi and beamwidth of 40–60 degrees. The size of the antenna is 7.5 mm × 8.4 mm × 1.0...
This paper proposes a cost-effective antenna package suitable for the mobile terminal of the wireless file-transfer system. The antenna package provides the end-fire radiation from the open-ended post-wall waveguide built into the side of the package. The antenna package, in which a 60-GHz CMOS chip is attached, is mounted on the edge of a printed circuit board by the ball-grid-array assembly. The...
