The effect of users on the efficiency of mobile terminal antennas at 15GHz, 28GHz and 60GHz is studied in this paper. It is performed using three four-element planar arrays. The first operates at 15GHz with a bandwidth of 0.74 GHz, the second at 28GHz with a bandwidth of 2.5 GHz and finally the third antenna at 60GHz with bandwidth of 12.5 GHz. The effect of a user’s finger is studied when being placed on four different locations over each antenna element, with six distances between the antenna…
