Abstract
An antenna is provided and characterized by searching a look-up table for emission angle information according to an incident angle of a radio frequency input signal and driving an antenna array to emit a radio frequency output signal in a direction corresponding to an incident direction of the radio frequency input signal according to the emission angle information.
Claims7
An antenna signal transmission apparatus, comprising:
- a plurality of antennas forming an antenna array for receiving a radio frequency input signal;
- and
- a signal transmission control module comprising a plurality of phase adjustment units comprising a look-up table unit and searches the look-up table units according to an incident angle of the radio frequency input signal for an emission angle information of the antennas corresponding to the incident angle;
- wherein the phase adjustment units send a feed signal according to the emission angle information to trigger the antennas to generate radiating beams, thereby causing the antenna array to emit the radio frequency output signal;
- wherein the emission angle information comprises information about a phase difference between the radiating beams generated from the antennas, wherein the phase difference information depends on a phase difference between the radio frequency input signals received by the antennas.
