Radio frequency coupling and transition structure

An integrated circuit device is formed to include a plurality of vias that connect an antenna to a ground reference. This configuration of the integrated circuit device provides an electrical path from the antenna to ground, thereby preventing the buildup of charge at the antenna. The vias thereby reduce the likelihood of a potential difference between components of the integrated circuit device and the antenna, in turn reducing the likelihood of electrostatic discharge at the integrated circuit device.
