Design of package cover for 60 GHz small antenna and effects of device box on radiation performance

This paper shows the simulated performance of the small antenna with the effects of the package cover and the device box at 60 GHz band. The total thickness of the package has been reduced from 2.6 mm to 1.4 mm by using the designed cover. The gain is enhanced and the reflection is suppressed lower than -15 dB by using different ways of packaging. On the other hand, the small antenna is put in a 120 mm × 75 mm × 30 mm polycarbonate box in simulation. The radiation performance due to the dielectric box case in practical device has also been simulated and discussed.
