主权项

1. A smart antenna system for transmitting and receiving comprising:
a. a plurality of dual band individual antenna patches tuned for both 1.6 GHz and 2.5 GHz; b. wherein each of said individual antenna patch is connected to a phase shifter; c. wherein said phase shifter comprises discrete circuit paths between radio frequency switches; d. wherein said discrete circuit[s] paths are configured in length to optimize the reception of certain wavelengths from said plurality of individual antenna patches by providing an electrical delay so that desired frequencies are constructively interfered and undesired frequencies are destructively interfered; and e. a microcontroller configured to select at least one of said discrete circuit paths and to switch between said discrete circuit paths to maximize the reception of the desired frequency.
