1. A system comprising:
a frame;
a printed circuit board (PCB) mounted to the frame; and
at least one antenna electrically connected to the PCB via an antenna feed,
wherein the antenna is to operate within a specified frequency range,
wherein the frame includes a plurality of separate, electrically isolated locations to which electrical current is routable, each of the locations radiating at different frequencies,
wherein a specified location of the frame is selected from the plurality of separate, electrically isolated locations on the frame, such that electrical current is routed to the selected specified location on the frame, the specified location being selected on the frame to act as a parasitic arm that provides constructive interference within the specified frequency range, and
wherein electrical current flowing to the antenna is routed to the selected location on the frame to create the parasitic arm, such that the parasitic arm radiates in conjunction with the antenna, providing constructive interference in the specified frequency range.
