Abstract
Provided is an antenna apparatus including: a signal splitter configured to generate a second signal including N equal-phase signals by splitting a first signal received from a signal source; a signal source virtual beam adjustor configured to generate a third signal including N signals by shifting a phase of each signal included in the second signal; a transmission beam adjustor configured to generate a fourth signal including N signals by shifting a phase of each signal included in the third signal by 0 degree or 180 degrees; and a transmitter including N transmission antennas transmitting respectively transmitting the N signals included in the fourth signal.
Claims20
An antenna apparatus comprising:
- a signal splitter configured to generate a second signal including N equal-phase signals by splitting a first signal received from a signal source;
- a signal source virtual beam adjustor configured to generate a third signal including N signals having a virtual focus at one point by shifting a phase of each signal included in the second signal;
- a transmission beam adjustor configured to generate a fourth signal including N signals by shifting a phase of each signal included in the third signal by 0 degree or 180 degrees;
- and
- a transmitter including N transmission antennas respectively transmitting the N signals included in the fourth signal.
An antenna apparatus comprising:
- a receiver comprising N signal receivers;
- a signal source virtual beam adjustor configured to shift a phase of each of N signals received by the N signal receivers to have a virtual focus at one point;
- a transmission beam adjustor configured to shift a phase of each of the N signals that are phase-shifted by the signal source virtual beam adjustor, by 0 degree or 180 degrees;
- and
- a transmitter comprising N transmission antennas respectively transmitting the N signals that are phase-shifted by the transmission beam adjustor.
