US Patent 10965035 Reconfigurable antenna systems with ground tuning pads

Reconfigurable antenna systems with ground tuning pads are provided herein. In certain configurations, an antenna system includes a module substrate including a ground plane and a ground tuning pad configured to receive a ground voltage from the ground plane. The antenna system further includes an antenna element and a tuning conductor that is spaced apart from the antenna element and operable to load the antenna element. Furthermore, a switch is electrically connected between the tuning conductor and the ground tuning pad, and operates to selectively connect the tuning conductor to the ground plane by way of the ground tuning pad to provide tuning to the antenna element.
