1. An electronic device, comprising:
an array of antenna elements having associated predefined fields of view configured to receive wireless signals associated with at least a satellite and to provide corresponding electrical signals,
wherein at least two of the antenna elements in the array of antenna elements have different predefined fields of view;
one or more switches configured to selectively couple to antenna elements in the array of antenna elements; and
one or more integrated circuits, coupled to the one or more switches, configured to receive the electrical signals, wherein the one or more integrated circuits are configured to:
dynamically select at least a given antenna element in the array of antenna elements based at least in part on a location and motion of the electronic device, and a location and motion of at least the satellite;
provide control signals to at least one of the one or more switches to selectively couple to at least the given antenna element; and
receive, via the given antenna element, the electrical signals,
wherein the wireless signals have carrier frequencies in a V band of frequencies or a W band of frequencies and
the array of antenna elements has improved power efficiency, pointing accuracy and isotropic gain relative to an array of antenna elements without switched antenna elements.
