Abstract

In this paper, we propose a novel method to mitigate the strong shadowing effect a nearby finger has on the antenna of a handheld communications device operating at 60 GHz, by introducing reflectors on the device. When the finger is located at the distance of 3 mm of the antenna, it causes strong shadowing and the far-field radiation attenuation behind the finger is 25-34 dB. In this paper, we show that a parabolic reflector 'collar' that is placed around the antenna array can significantly reduce the shadowing in the far-field. With the collar, the far-field radiation behind the finger is improved by 19-25 dB, making the array usable even when covered by a finger. The effect of reflector size and location is studied.
